Answer:
Surface area = 85.84 ft²
Step-by-step explanation:
Considering the fact that large rectangle area = 6 x 12 = 72 ft²
Also, the two triangles area => 2(0.5 * base * height) = 2(4 x 3.46 x 0.5) = 13.84 ft²
Hence, the total surface area is
72 + 13.84 = 85.84 ft²
Therefore, the surface area of the fabric is 85.84ft²
