Answer:
308.6 square feet
Step-by-step explanation:
7 * 4 = 28
now that you have the are for the rectangles, you can multiply that by 5 because there 5 sides in a pentagon.
28 * 5 = 140
Now time for the bases, the base is 84.3 square feet, since there are two of them, you multiply that 84.3 by 2 and get an answer of 168.6 square feet.
The total surface are of the object is the area of the two bases plus the area of the 5 rectangles.
140 + 168.6 = 308.6 total square feet.
