The tile is bigger than the area that you want to cover (12x12 > 10x11) so one tile will do. <><><><><> However, if you meant 12x12 INCH tiles, and a 10x11 FOOT room, you would need 110 tiles.

If you're talking floor tiles as opposed to wall tiles and by 12x12 you mean they are 12 inches square, then the answer is 300. Because each tile is one square foot and a 15'x20' room is 300 square feet. Simple, eh?

LXW is the formula for area so it's 4X6=?? Then its 12X12 tiles = 1 sq ft each so looks a lot like 24 tiles

Since there are no units given it is not possible to answer the question. The units used for measuring the tiles must be different from those used for the room.
