width times length 10 x 12 room needs 120 tile.
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.
You would need 111 tile, but with waste you will want to get 125 tile.
12X12=1 Square Foot of tile. You would need 49 Square Feet of tile.
A 12x12 tile is 1 sq foot, so you will need 198 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?
A 12x12 tile is 1 sq foot, so you will need 198 tiles.
Whatever the lxw of a single tile is ,divide that into the lxw of the room.
You calculate the sqft of the room, a sqft is still a sqft no matter what the tile dimensions are
The units of measurement for neither the tile nor the room are given. I can therefore assume that it is a 10 ft x 10 ft room and a 12 ft by 12 ft [carpet] tile. So answer: less than 1 tile.

Each tile is one square foot. So you need 126 of them, but allow for spoilage.
The answer depends on the measurement units used for "12x12": feet, metres, yards or some exotic measure? Without that information the question cannot be answered.
