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.
I believe it's 36. The vertices have the same x coordinate so I found the difference between the y coordinates.
