A trapezoid is a quadrilateral with exactly one pair of parallel sides.

Formula for area:
A = (1)/(2)(^(b)1 + ^(b)2)(h)

In this formula, the bases are the parallel sides.

Now plug the information into the formula.


A = (1)/(2) (3 + 5)(9).

Follow your order of operations, simplify inside the parentheses first.


A = (1)/(2)(8)(9).

(1/2)(8) is 4 so we have (4)(9) which is 36.

So the area of the trapezoid is 36.
