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
