How many square yards of carpet are needed to cover a floor that is 15 feet by 20 feet?

You would need 100 square yards of carpet. 15x20=300 square feet and there are 3 feet in one yard so... 300/3=100 square yards.

--------------------------------------

Math: 15 feet X 20 feet = 300 Square feet

There are 9 square feet (3feetX3feet) in a square yard -

300 / 9 = 33 1/3
