Answer:


b = (2A -Bh)/(h)

Explanation:

The given relation is :


A = (1)/(2) (B + b)h

We want to solve for b

We multiply both sides by 2 to get


2A = (B + b)h

Divide through by h


(2A)/(h) =B + b

Subtract B from both sides


(2A)/(h) - B = b

We now simplify the left hand side to get


(2A -Bh)/(h)=b

Or


b = (2A -Bh)/(h)
