The Henderson’s have a vacation home in the mountains. To prevent snow from accumulating on top of the
roof, the Henderson’s house is an A-frame so named because the front and back of the house are shaped
like a triangle and look like the letter “A”. The house is in the shape of a triangular prism.
Mr. Henderson plans to put new shingles on the roof, so he needs to calculate the entire roof area. Based on
the dimensions of the house, how many square feet of shingles will Mr. Henderson need to cover the roof?
