Question

9) Mrs. Thompson is putting new tile on her bathroom

floor. Each tile measures 2 inches on each side. The
bathroom floor is 3 feet long and 2 feet wide. How
many tiles will she use to cover the entire floor? (L 1-4)

Answer 1

To cover the entire floor, Mrs. Thompson will need 216 tiles.

Step-by-step explanation:

To find out how many tiles Mrs. Thompson will need, we first need to calculate the area of the bathroom floor. The formula for finding area is length x width. The length of the floor is 3 feet and the width is 2 feet, so the area of the floor is 3 x 2 = 6 square feet.

Since each tile measures 2 inches on each side, we need to convert the area from square feet to square inches to match the size of the tiles. Since 1 foot is equal to 12 inches, 1 square foot is equal to 12 x 12 = 144 square inches. Therefore, the area of the floor in square inches is 6 x 144 = 864 square inches.

Now, to find out how many tiles will be needed, we divide the area of the floor in square inches by the area of each tile in square inches. Each tile has an area of 2 x 2 = 4 square inches. So, 864 square inches ÷ 4 square inches = 216 tiles.
