Answer:
A floor 9 feet by 12 feet, is to be tiled with 4-inch-by-6-inch tiles.
Explanation:
How many tiles are needed to cover the floor?
9 ft is 9 x 12 = 108 in
12 ft is 12 x 12 = 144 in.
The area of the floor is 108 in x 144 in = 15,552 sq. in.
Each tile is 4 in x 6 in = 24 sq. in.
Dividing 15,542 sq. in by 24 sq. in gives an answer of 648 tiles.
