First you have to change the inches to feet. So you divide 13/12 (because there are 12 inches in one foot). So the tiles are now 1.08 feet x 1.08 feet. Multiply the two sides together to get the area of one tile. 1.08 x 1.08 = 1.16 square feet.
Now divide the whole area of the room (150 square feet) by the area of one tile to find how many tiles are needed.
150/1.16 = 129.3 tiles.
(When ordering tiles you should always order a few more to cover any breakages etc. )

18*18 = 324 tiles.
14 x 12 = 168 square feet - that is 168 tiles since each is one square foot
240 square tiles are needed

Each tile will cover 100 square inches. 12,000 square feet is 1,728,000 square inches. You will need 17,280 tiles.
Floor area = 12 ft x 18 ft = 216 square feet. There are 4 six-inch square tiles needed for each square foot, so 864 tiles are needed.

Each tile is 1 square foot.
Scrabble tiles are 0.75 inch × 0.75 inch square. Therefore, one square foot of Scrabble tiles will include 256 tiles in a square of 16 X 16 tiles.
