The house is 20.5 feet by 10 feet. The porch measures 6 feet by 4.5 feet. The house and the porch need shingles. How many square feet of shingles will be needed to roof the house and the porch?
House = 20.5 * 10 = <<20.5*10=205>>205 square feet
Porch = 6 * 4.5 = <<6*4.5=27>>27 square feet
205 + 27 = <<205+27=232>>232 square feet
232 square feet of shingles will be needed.
