Question

The formula for a trapezoid relates the area A, the two bases, a and b, and the height, h. A=1/2h(a+b) Solve for h.

Answer 1

Given the formular for relating the area A, the two bases, a and b, and the height, h of a trapezoid is given by

$A= \frac{1}{2}h (a+b)$

We solve for h as follows:

$A= \frac{1}{2}h (a+b) \\ \\ \Rightarrow2A=h (a+b) \\ \\ \Rightarrow h= \frac{2A}{a+b}$

Answer 2

h=\frac{2A}{a+b}
