Question

Use the formula A = Ibh find the height to the nearest tenth of a triangle with a base of 15 and an area of 200.​

Answer 1

26.7

Explanation:

The formula of an area of a triangle:

`A=(1)/(2)bh=(bh)/(2)`

b - base

h - height

We have b = 15, A = 200.

Substitute:

`200=(15h)/(2)`

`200=7.5h` divide both sides by 7.5

`(200)/(7.5)=(7.5h)/(7.5)`

`h\approx26.7`
