14x14=156 sq ft 12x12=1sq ft assuming no waste (and there always waste) = 156 tiles are needed...(always buy an extra 10-15% fr wastage/broken ones etc )
One 12' x 12' cover will cover 144 square feet, so just one but you might have to cut it.
If the tiles are 12x12 inches square - you would need... 75 !

80 if the tiles are 12x12 - 12x12 is one square foot covering 80 you would need 80 tiles
A 12x12 tile is 1 sq foot, so you will need 198 tiles.
You need 0.52, so about a half.because a single 12x12 tile has an area of 144.
123 will cover it. Get extras.
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.
Since each 12x12-inch tile is one square foot, you will need 750 of them.
