A 12x24 tile is 2 square feet. There are 120 tiles that would be needed.
Each tile will cover 2 square feet. So you will need 12.5 tiles.
52, assuming no waste. 12" x 24" =2 sq. ft. divided into 104 sq. ft. = 52
It depends on the units used to measure the tile: 12inch*24inch, 12cm*24cm or some other, unspecified unit.
288 square feet.
You would have 79 tiles.
The tiles are not 12X24 they are 1 foot X 2 Foot and that makes the 1'x2'=2' sq feet each tile. 110 sq feet to cover makes the equation look like 110 divided by 2 = 55 tiles
288 square feet.
49 tiles
That would depend on the size of the tiles.
You would need 173 tiles (you would have fractions of tiles left over)
