Question

The area of the floor in a square room is 225 square feet. The homeowners plan to cover the floor with rows of 6-inch by 6-inch tiles. How many tiles will be in each row?

Accepted Answer

The length of each side of the room is 225=15 feet, or 1512=180 inches. Since each tile has a length of 6 inches, each row needs 180/6=30 tiles.
