The Mazurskys decide to retile their mud room in 18 in. by 18 in. tiles. If their mudroom is 5 ft 6 in. by 13 ft, how many tiles
Mrac [35]

The area of one tile is 18 x 18 = 324 square inches.


Convert the dimensions of the room into inches:

5 ft 6 in. = 66 inches.

13 ft = 156 inches.

The area of the room is: 156 x 66 = 10296 square inches.


To find the number of tiles needed, divide the total area of the room by the area of one tile:

10,296 / 324 = 31.78, which means they will need 32 tiles.
