Assume you are working on a house the length of the house is 50 feet, the width is 30 feet, and from the ground to the gable is 10 feet. The height of the triangle prism on top is 6.5 feet. If you are going to shingle the roof of this house, how many square feet should you plan for?

Assuming no overhang at the eaves, the length of the roof is 50 ft and the width on each side is
w^2 = 15^2 + 6.5^2
w = 16.35
So, the area is 2 * 50 * 16.35 = 1635 ft^2
