How many square feet o carpet do you need to buy if you have 3 rooms that are 12ft by 12ft and 2 rooms that are 15ft by 20ft?

Answer 1

= (3 rooms X 12 ft X 12 ft) + (2 rooms X 15 ft X 20 ft)

= (3 X 144 ft^2) + (2 X 300 ft^2)

= (432 + 600) ft^2 = 1032 square ft

OR you can write this as 1032 ft^2, which is just feet raised to the second power.
