Question

The formula for the area of a triangle is a=1/2bh. solve the formula for h. a triangle has a base of 7cm and an area of 28cm squared. what us it's height

Answer 1

28=1/2(7)h
Divide by 7 on both sides giving you
4=1/2h
Multiply by 2 on both sides giving you
h=8
Therefore, the height is 8cm.

Answer 2

Answer: 8 cm

Explanation:

Given : The formula for the area of a triangle is
`a=(1)/(2)bh`

If a triangle has a base of 7 cm and an area of 28 cm squared.

The substitute the values of b = 7 and a = 28 in the above formula, we get

`28=(1)/(2)(7)h`

Divide 7 and multiply 2 on on both sides, we get

`h=(28*2)/(7)=4*2=8\ cm`

Hence, the height of triangle = 8 cm
