Which of the following is the height of the special trapezoid if wx = 18 , yz = 18 & the area is 144^2

Area of a trapezoid formula:

A = 1/2(Base1 + Base2)*height

I will assume that WX and YZ are the two bases, since that's the only thing that logically makes sense to answer the question.

Plug in what we know
I believe the Area is meant to be 144 unit^2, as no area is ever given as 144^2

144 = 1/2(18 + 18) * h

solve for h

144 = 18 * h

h = 144/18

h = 8

The height is 8.
