Answer:
42 ft squared
Explanation:
First you must find the sides and heights of each of the shapes, for instance, the trapezoid, the rectangle, and the triangle. After you find the sides and height you would solve for the area using the three area formulas for each shape. Then once you have the three individual areas you would just add each answer together and get 42.
Formulas:
Trapezoid = 1/2(b1 + b2)h
Rectangle = b x h
Triangle = 1/2bh
