How do you find the area of a square? How to find the area of a square?

The area formula for a square is:

1. The area of the square = the length of the side of the side = a a (where a is the side length of the square) is represented by letters: s = a (s refers to the area of the square).

2. The area of the square =DiagonalDiagonal 2

Squares are special parallelograms.

One. That is, a group of parallelograms with equal adjacent sides and one angle is at right angles is called a square, also known as a regular quadrilateral.

The square has all the characteristics of a rectangle and a rhombus.

Decision theorem for squares:

1.A diamond with equal diagonals is a square.

2.A diamond with a right angle is a square.

3.Rectangles with diagonal lines perpendicular to each other are squares.

4.A set of rectangles with equal adjacent sides is a square.

5.A group of parallelograms with equal adjacent sides and one corner at right angles is a square.

6.A parallelogram with diagonal perpendicular to each other and equal to each other is a square.

7.Quadrilaterals with equal diagonals and bisected perpendicular to each other are squares.

8.A group of adjacent sides with equal sides and three quadrilaterals with right angles are squares.

9.A quadrilateral that is both a diamond and a rectangle is a square.

Because the length and width of the square are equal, it is called a square. In all kinds of graphic areas, there are rectangles, squares, trapezoids, circles, and irregular figures, all kinds of shapes, rectangles are figures with unequal length and width, and squares are equal in length and width, and you look at them from the same side, so we call them squares. When the square and rectangle are of the same circumference, the area of the square is the largest.

According to the characteristics of the square and the area of the square = the length of the side, the length of the side can be calculated.

Cube surface area.

Formula: surface area = base area x 6 = edge length x edge length x 6; The volume of the cube = edge length x edge length x edge length. A three-dimensional figure surrounded by six identical squares is called a cube.

A straight parallelepiped with a square side and bottom surface is called a cube, that is, a hexahedron with equal edges and lengths, also known as a "cube"."Regular hexahedron", the cube is a special cuboid.

A square is a special parallelogram and is also a special rectangle.

Within the same plane: A quadrilateral with all four sides equal and one corner at a right angle is a square. There is a set of rectangles with equal adjacent sides that are squares. A diamond with a right angle is a square. The squares are diagonally equal and bisected perpendicular to each other.

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 area formula for a square.

If a is the length of the side of the square, v is the diagonal of the square, s is the area of the square, and c is the perimeter of the square, then: v = 2a, s = a = v 2

Decision theorem for squares:

2. A diamond with a right angle is a square.

3. Rectangles with diagonal lines perpendicular to each other are squares.

9. A quadrilateral that is both a diamond and a rectangle is a square.

Square side length = areaThe area of the square is equal to the square of the side length: s=a*a, which is the side length multiplied by the god pure side length.

Because the sides of the square are equal in length, the side length = area, the side length = area, the area is generally positive, and the square makes sense.

The square area = side length x side length, so the side length = area square.

For example, if the area of a square is 16 square meters, the side length = 16 square meters = 4 meters.

The length of the side is = s (s is the area). The length of the side of the square is equal to the area of the square to the square and the square is taken as the positive root.

The process is as follows:

1) First set the area of the square as s, and then according to the formula of the area of the square, it can be obtained: area = side length side length.

2) So we can get the side length = s. And because the side length must be greater than 0, the side length = s. The text is expressed as the length of the side of the square is equal to the area of the square to the square to the square square.

Extended Information: The Nature of Squares:

1) Two sets of opposite sides are parallel to each other; All four sides are equal; Adjacent edges are perpendicular to each other.

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

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

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

Square Rectangle Common Area Perimeter Formula:

How can the side chief be stupid?

Then let me explain.

High-powered answers. Answer questions hard, don't live hard.

Pay attention first. The area of the square is equal to the square of the side length: s=a*a, which is the side length multiplied by the side length.

Knowing the area of the square s, to determine the length of the side of the square, the method is as follows.

side length a = s

a=root number s example: the area of the square is known to be 16, find the side length of the square.

a²=16a=4
