My question is: 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? Your thoughts:
House = 20.5 * 10 = 205 square feet. Porch = 6 * 4.5 = 27 square feet. 205 + 27 = 232 square feet. 232 square feet of shingles will be needed. The final answer: 232.
