Carmen Schmitt · Answer 1

312 square feet

Step-by-step explanation:

Each square is 11 x 12 feet which is 132 times 2 for the front and back, which is 264 feet. Then, the triangles at the top have a height of 4 feet (15-11) and a base of 12 feet, so because there are 2 triangles, the result is 12x4=48. Then, you add 264 to 48 and all done.
