The side length of the square is disproportionate to the area 5

First, the side length of a square is disproportionate to the area. So 1) is wrong. It can be said that it is directly proportional. Or that the square of the length of the side is proportional to the area.

2) Not true. It should be said that in the same plane, two straight lines that never intersect are called parallel lines.

3) Not true. 4) Not true. February 2006 had 28 days.

So there is no right answer.

There is no right answer.

1.After the grade has taught about proportionality, I have two questions: First, what is the ratio of the length of the sides and the area of the square?

Second, the length of the rectangle must be certain, and what is the ratio of its width and circumference? As soon as students look at the question, they immediately make a mistake in judging that it is proportional. What is this The main difficulty in the textbook has not been overcome.

In my reply to proportionality, I have repeatedly emphasized three points: (1) The proportionality of two related quantities must be based on the premise that the quantity of one type is fixed, and all four sides of the square are equal, and if one side changes, the other sides also change.

There is no fixed amount of it, so the side length is not proportional to the area. (2) The importance of "same multiple" is fully emphasized.

collar is associated with two quantities, although one of the quantities expands or shrinks, and the other quantity also expands or shrinks, but if they expand.

or the reduction is not the same, and the two quantities are still not called proportional quantities. For example, the length of the rectangle is fixed, and the width and circumference are fixed.

Disproportionate, because the width expands or shrinks, the perimeter, although also expands or shrinks, it is not the same times as the expansion or contraction.

Number. Therefore, it is not proportional. (3) Tell students that if two quantities are proportional to each other, then a self-varying phase of quantity.

When given to one factor in multiplication, a fixed quantity is equivalent to another factor, and another quantity that changes with it is equivalent to the product.

When judging proportionality, if we can affirm that there is a relationship between the factor and the product of the two quantities, the two quantities must be proportional.

2.Two straight lines that do not intersect in the same plane are parallel lines. The case of straight lines with different planes is not taken into account.

3.Two numbers of coprime can be any kind of number, as long as two are together and only the common divisor 1 is a coprime number; Further, three cases of certain coprime are obtained: two different prime numbers, 1 and all natural numbers, and two adjacent natural numbers.

Two composite numbers such as 4 and 9 are coprime numbers. So this assertion is wrong.

4.Apparently it should be 28 days.

There is nothing wrong with this question!

1. They are proportional.

2. In the same plane, two straight lines that do not intersect are called parallel lines.

and 8 are both composite numbers, but their common divisor is , and only the greatest common divisor of several numbers is 1, and they are cozy.

4. Just look at the calendar.

So 1 is correct.

It is proportional to the square of its side length, and increases with the increase of the side length, but the side length is not proportional to the area.

Only 4 is likely to be right. The area of a square is proportional to the length of its sides, and two straight lines that do not intersect may also be opposite. 3. Needless to say.

Disproportionate. Because his side length is not necessarily.

One side length change.

The other one will change, too.

Wrong: The area is the square of the side length, are you confused? If it is how many times it can be proportional.

False High school students say it's wrong, younger students say it's right. It depends on whether you study flat or three-dimensional. Wrong, wrong.

Yes, the first one is right, and if you learn the cube, you know that 2 is not right, and 3 and 4 are not right, hehe.

No mistake. Only 1 is right.

1, 2, 3 are not right! 4. Time to see the problem!

The area of the square. sa^2

That is, s=a*a

Because the length of the sides is not a fixed value, the area of the square is not proportional to the length of the sides and is not inversely proportional.

The area of the square is disproportionate to the length of the sides, and the reasons for this are as follows:

Whether proportional or inversely proportional, there must be a quantity in which it is certain (or invariant).

Because one of the characteristics of the square is that all four sides of the square are of equal length. The area of the square = the length of the side The length of the side = the length of the side

In the above formula, a certain amount cannot be found, if one side length expands, the other side lengths must also expand accordingly, otherwise it is not a square. So, the side length and area of the square are disproportionate.

The area formula for a square is:

Area = side length, expressed in letters: s = a (s refers to the area of the square, a refers to the length of the side of the square).

A square is a special rectangle, a special rectangle, rectangular area = rectangular area = length and width;

In letters, it is: s=ab (s is the area of the rectangle, a is the length of the rectangle, and b is the width of the rectangle).

The side length of a square is disproportionate to its area.

The side length of the square is proportional to the circumference. The area of the square changes with the change of the side length, but the ratio of the area of the square to the side length is not fixed, so the side length and area of the square are not proportional.

The area of the square is not proportional to the length of the sides, because when one side of the square changes, the other side also changes, and it is naturally not proportional without a certain number.

According to the meaning of positive proportion and inverse proportionality, in the proportional quantity relationship, there is a certain quantity, two changing quantities, and if all three quantities are changing, then there is a disproportional relationship

Solution: The area of the square = the length of the side The length of the side, when the side length of the square changes, the other side of it also changes, and the area also changes at the same time, these three quantities are all changing, so the area of the square is not proportional to the length of the side

Because the title doesn't say that the side length is certain! ☁️

The area of a square is the square of the length of the sides.

The area of the square is disproportionate to the length of the sides for the following reasons:

The relationship between the area of the square and the length of the side is: the area of the square is equal to the length of the side The length of the side, if the side length is expanded n times, the area of the square will be expanded by n times of the square, such as the side length of the square is 4, the area is 4 2 = 16, if the area is expanded by two times, the side length is 8, the area is 8 2 = 64, the expansion is 4 times, the proportion of the change between the two is not the same, so the area of the square and the side length are not proportional.

The meaning of proportion is: when one number changes, another number also changes together, and the ratio of the two numbers changes is the same, then the two numbers are said to be proportional.

The area of the square is disproportionate to the length of the sides for the following reasons:

The meaning of proportion is: when one number changes, another number also changes together, and the ratio of the two numbers changes is the same, then the two numbers are said to be proportional.

The area of a square is not proportional to the length of its sides. To determine the ratio between two related quantities, it depends on whether the ratio of the two quantities is a certain or a certain product. If the ratio is constant, it is proportional; If the product is constant, it is inversely proportional.

Because 1 1 = 1, 4 2 = 2 9 3 = 3, 16 4 = 4, that is, the ratio of the area of the square to the length of the sides is not fixed.

The main features of the square

1. Edges: two groups of opposite sides are parallel to each other; All four sides are equal; Adjacent edges are perpendicular to each other.

2. Inner angles: All four corners are right angles.

3. Diagonal: the diagonals are perpendicular to each other; The diagonals are equal and bisected from each other; Each diagonal is bisected by a set of diagonals; The diagonal lines are equal.

4. Symmetry: It is both a central symmetrical figure and an axisymmetric figure (with four axes of symmetry).

5. The square has all the properties of a parallelogram, a rhombus, and a rectangle.

6. Special properties: a diagonal line of the square divides the square into two congruent isosceles right triangles, and the angle between the diagonal and the side is 45°; The two diagonal lines of the square divide the square into four congruent isosceles right triangles.

7. Draw the largest circle in the square, and the area of the circle is about the area of the square; The circumscribed circle area of the square is about 157% of the area of the square.

8. The square is a special rectangle.

9. The midpoint quadrilateral of the square is a square, and the ratio of the area is 1:2.

The area of the square is disproportionate to the length of the sides.

Because, the area of the square side length = side length, (the area varies with the change in the side length, the ratio is the side length, and the ratio is not quantitative), because the ratio is not fixed. Therefore, the area of the square is not proportional to the length of the sides.

The side length and circumference of the square are proportional to Lu Yushen's example. The area of the square is changed with the change of the side length, but the ratio of the area of the square to the side length is not certain, so the side length and area of the square are not proportional.

The area of the square and the side length are not proportional to the side length, the reason is: the relationship between the area of the square and the side length is: the area of the square is equal to the side length The side length, if the side length is expanded n times, the area of the square will be expanded by n square times, such as the side length of the square is 5, the area is 5 2 = 25, if the area is expanded by two times, the side length is 10, the area is 10 2 = 100, and the expansion is 4 times, and the specific state resistance of the two changes is not the same, so the area of the square and the side length are not proportional.

The meaning of proportionality is: one number expands n times, and the other number also expands n times together, and the value of the expansion of the two numbers is the same, then Fan Shuchun says that the two numbers are proportional.

Square area formulaThe formula for the area of a square is the length of the side of the side.

A parallelogram with a right angle and a set of adjacent sides equal is a square.

Nature of the square:

1. The two groups of opposite sides are parallel to each other, the four sides are equal, and the adjacent sides are perpendicular to each other.

2. The four corners are 90°, and the sum of the inner angles is 360°.

3. The diagonals are perpendicular to each other; The diagonals are equal and bisected from each other; Each diagonal is bisected by a set of diagonals;

4. It is both a center-symmetrical figure and an axisymmetric figure (with four axes of symmetry).

The area of the square is disproportionate to the length of the sides.

Because, the area of the square side length = side length, (the area varies with the change in the side length, the ratio is the side length, and the ratio is not quantitative), because the ratio is not fixed. Therefore, the area of the square is not proportional to the length of the sides.

What you are talking about here should be a linear ratio, an area radius radius (not a constant, so it is not proportional).

When the side length of a square increases by 1 3, the ratio of the area of the original square to the new square is

Because the ratio of the length of the sides of a square to its area is not a fixed value, it is disproportionate.

"The side length and area of the square are "disproportionate."

Area: Side Length = Side Length (the value is not necessarily, it is changing).

A is proportional to b, which means that there is a constant k (not zero) such that; a=kb

The side length of the square is set to x, and its area is x 2, which is of course disproportionate.

Disproportionate, area = square of side length.

The area of the square is disproportionate to the length of the sides.

Because, the area of the square side length = side length, (the area varies with the change in the side length, the ratio is the side length, and the ratio is not quantitative), because the ratio is not fixed. Therefore, the area of the square is not proportional to the length of the sides.

Conclusion: Not proportional. Reason: The two variables y are proportional to x, meaning y=kx (where k is a constant that is not 0) and the relationship between the area s of the square and the length of the side a is s=a 2So they are not proportional. Hope it helps!
