The front wall of your shed is in the shape of a trapezoid. The bottom measures 12 feet, the top measures 10 feet, and the height is 6 feet. Calculate the area of the front wall of your shed.

The area of a trapezoid is the average of its two parallel sides multiplied by its height. The parallel sides are 12 feet and 10 feet, so the area is ((12 + 10) ÷ 2) × 6 = 11 × 6 = 66 square feet. The correct choice is d, 66 sq. ft.
