Answer:

Area = 2,031ft^2

Total weight of gravel on the roof = 24,372 pounds

Step-by-step Explanation:

The area Adams planned to cover with gravel can be divided into 3 rectangles as shown in the diagram attached.

We would have 3 rectangles. See the attachment below to check out how we arrive at the dimensions of the 3 rectangles.

Area of rectangle = L*W

Area to be covered by gravel = area of rectangle 1 + area of rectangle 2 + area of rectangle 3

Area to be covered with gravel = (30*17) + (13*9) + (52*27)

Area = (30*17) + (13*9) + (52*27) = 2,031ft^2

Total weight of gravel on the roof = 12 pounds per square foot multiplied by total area of the roof to be covered = 12 * 2031 = 24,372 pounds
