Answer:

Square feet of tarp that will cover the roof = 400 square feet.

Step-by-step explanation:

Area of roof building = L × W = 20 × 15 = 300ft^2

The roof has a single peak running along the 20 foot building with 45°.

Therefore, the pitch of the roof is given by :

Pitch = Rise / Span

Rise= 20feet

Span = 15 feet

Angle between them is 45°

Pitch = 20/ 15 = 1.33

Therefore, the square feet of tarp that will cover the roof will be = 300 × 1.33 = 400 ft^2
