Question

The following formula gives the area A of a trapezoid, where b and c are the bases of the trapezoid and h

is the height:
A=
(6+c)h
Rearrange the formula to highlight the height.
h

Answer 1

`h = (2A)/(b + c)`

Explanation:

Given

`A = (1)/(2)(b + c)h`

Required

Solve for h

We have:

`A = (1)/(2)(b + c)h`

Multiply sides by 2

`2A = (b + c)h`

Make h the subject

`h = (2A)/(b + c)`
