There are 12 inches in 1 foot so each tile is 1x1 ft.
This means nine tiles will fit along nine ft and twelve tiles will fit along twelve ft
The area of this would be 9x12 Which is 108
In conclusion 108 12x12 in tiles will cover 9x12 ft
If you mean 12x12 "inches", then each tile covers 1 square foot. We trust you can take it from there.

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.
1 and 1/3 tiles of 9 x 12 tiles will equal 1 square feet. Therefore, it will take 25 times 1-1/3 tiles or approx. 34 9x12 tiles to tile a 25 square foot area.
If 12x12 is 144... There would be 144 tiles in a box right?
144 tiles
If you mean 12x12 "inches", then each tile covers 1 square foot. We trust you can take it from there.

80 if the tiles are 12x12 - 12x12 is one square foot covering 80 you would need 80 tiles
Since a 12x12 tile is one square foot, then 38 12x12 tiles will cover 38 square feet.
