An 18 inch by 18 inch tile is one and a half feet by one and a half feet, or 3/2 ft by 3/2 feet.

Its area is two and a quarter square feet. (3/2 x 3/2 = 9/4).

The number of tiles needed is 121 divided two and a quarter.

That's 121 divided by 9/4 = 121 x 4/9 = 54 (rounding up to a whole number of tiles.

But this is the minimum number of tiles needed. The real answer will depend on the shape of the area to be covered, which determines how many tiles will need to be cut and how much wastage there will be.
