Answer 1

The answer is h = 2A/(b+c) .

Explanation:

You have to move all the unrelated terms to the other side by making h the subject :

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

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

`2A = (b + c)h`

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

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

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