The area of a triangle is 20 square centimeters, the base is 8 centimeters, find his height. Please

The area of the triangle is s=(base * height) 2

If the height is x, then 20=8x 2

x = 20 * 2 8 = 5 cm.

That is, the height of the triangle is 5 cm.

Using the area formula of the triangle, the area = 1 2 multiplied by the base multiplied by the height, and the height is set to x, so that 1 2 times 8 times x x = 20, x = 5

Hello! Solution: Set the height to x centimeters.

Triangle area = base * height 2

8*x÷2=20

8x=40x=5

A: The height of this triangle is 5 centimeters.

Triangle area formula: area = 1 2 base height.

Set the height to x8x 2=20

8x=40x=5

Untie; Let the height of the triangle be x

8×x÷2=20

x=20×2÷8

x=40÷8

x=5 A; The height of this triangle is 5 centimeters.

Because the formula for the area of the triangle is.

Area = bottom edge length height 2

So set the height to x, and list the equations according to the meaning of the question.

20=8×x÷2

20×2=8x

40=8xx=40÷8

x=5 solves x to be 8, which means that the height of the triangle is 8.

This question is mainly to examine the area formula of a triangle, and the difficulty of calculation is average.

Please refer to the above steps for details.

Triangle area formula: area = 1 2 base length times height. Equation: Let the height be x1 2 times 8 times x 20 The solution is x=5

The area of the triangle = the height of the base 2, what is the height of the known base length of 8? It can be calculated without column equations, because dividing by 2 gives 20, so when finding the high, it must be solved by inverse calculation, i.e.:

Result: The height of the triangle is 5. I hope you like it.

First of all, we take the area of the triangle 20 2=40 and divide it by 8=5, so the height of the triangle is equal to 5.

The equation is as follows: 8x 2=20

Solution: 4x=20

4x÷4=20÷4

x=5, so x=5.

The area of <> triangle is equal to the base multiplied by the height divided by two.

Let the height be x, according to the triangle area formula area area = base * height 2 columnable equations.

8*x÷2=20

4x=20x=5

Solution: If the height is x, then the area is (8+x) 2=208+x) 2=20

8+x=20÷2

8+x=10

x=10－8

x=2 high is 2.

Area of the triangle = base height 2

Solution: Let the height of the triangle be x.

8x÷2=20

8x=20×2

8x=40x=40÷8

x=5A: High is 5.

The area of the triangle = 1 2 The height of the bottom edge, from the question you can get 20 = 1 2 8 high, you can get the height = 20 2 8 = 5

Solution: Set the height to x.

8×x÷2=20

8x÷2=20

4x=20x=20÷4

x=5A: The area of the triangle is 20, the length of the base edge is 8, and the height is 5.

Let the height of the triangle be h.

Solution: 8h20, 8h20x2, h40, 8h5.

Answer: The height of the triangle is 5.

Solution: Let the height of the triangle be x.

It depends on the meaning of the title.

1/2×8×x=20

i.e.: 4x=20

x=5, so the height of the triangle is 5

solution, let the height of the triangle be h, which can be exemplified as follows.

Triangular area = base height 2).

8×h÷2=20

8×h=40

h=40÷8

h=5A, the height of the triangle is 5.

Assuming that the height is x, then the column equation gives 1 2 8 x = 20, 4 x = 20, x = 5

Area = 1 2 * bottom * height.

So 20=1 2*8*h

h=5 thanks.

Let the triangle be high as x, according to the title.

1/2×8x=20

4x=20x=5

Answer: The height of the triangle is 5

The triangle area formula = 1 2 base height.

Suppose the high is h20 = 1 2 8h

8h=40h=5

The height of the triangle is 5.

The area of the triangle is the formula base times the height divided by two, and the area is 20, then 20 2 8=5

Suppose the high is x

The area of the triangle = 1 2 bases * height.

20=1/2*8*xx=5

solution, set the height to h

Then the column equation gives 8h 2=20

4h=20h=20/4h=5

1500 multiplied by 2 divided by 50 equals 60The height is 60 cm.

Solution: Let the triangle be x centimeters high.

18x 2 triangular area of Celence.

9x the area of the triangle.

The area of the triangle is equal to the opening and bottom of the state multiplied by the height division.

Take two. The area of the triangle is 9x

You have two unknowns, so the result can only be algebraic, not an exact number.

The area of a triangle is 20 square centimeters, its height is 8 centimeters, and its base is centimeters.

Triangle area = 1 2 base height;

Bottom = 20 2 8 = 5 cm.

20 2 8,40 8,5 (cm);

A: The bottom is 5 cm

So the answer is: 5

According to the area of the triangle Bottom height 2, height triangle area 2 bottom, height 25 2 8 50 8 meters.
