Question

Does anyone know how to answer this question I'm having a lot of trouble with it?

Answer 1

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

Explanation:

Formula for the area of a trapezoid is,

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

Here b and c are the bases and 'h' is the height of the trapezoid.

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

2A = (b + c)h

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

Therefore, formula for the height of the trapezoid will be,

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