I did 1/2xhxb1 + 1/2xhxb2, which is the area formula I suppose, however, correct me if I am wrong, thanks~

OpenStudy (igreen):

A = 1/2(a + b)h

OpenStudy (igreen):

Where 'a' is the top and 'b' is the bottom of the trapezoid, and 'h' is the height.

OpenStudy (igreen):

The bottom edge would be 22.5(b) and the top edge would be 9.5(a) and the height is 8.

OpenStudy (igreen):

Your answer is correct.

OpenStudy (igreen):

1/2(22.5 + 9.5) = 16 16 * 8 = 128ft^2

OpenStudy (misssmartiez):

So it is correct?

OpenStudy (igreen):

Yes.
