Hays · Answer 1

The area of a trapezoid is calculated by the expression given as:

A = 1/2h (a + b)

To solve for h, we need to transfer terms to the one side leaving h only to the other side. It is done as follows:

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

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

2A / (a+b) = h

Therefore, the correct answer from the choices listed above is the second option, h = 2A / (a+b).
