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 = <T>multiply(20.5, 10)=205.0 square feet
Porch = 6 * 4.5 = <T>multiply(6, 4.5)=27.0 square feet
205 + 27 = <T>add(205, 27)=232 square feet
232 square feet of shingles will be needed.
