A rectangular bedroom is 10 feet by 12 feet. How many square titles that are 4 inches on each side must be used completely to cover the floor?

1,080

Why:

First. you have to turn the feet into inches which would make the room 120in. by 144in. and the area of the room would be 17,280 square inches.

Then you have to find the area of the square tiles, and since the sides of the square are the same length, 4x4=16

Last, you have to divide 17,280 by 16 which would give you 1080 tiles
