A 24" by 18" tile is 432 square inches or three square feet.
2.25 square feet
There are 144 18 square inch tiles in an area of 18 square feet.
If each tile is 1 1/2 feet by 1 1/2 feet, use the decimal equivalent to do the math: 1.5 x 1.5 = 2.25 square feet.
There are 1.5 times 3 = 4.5 square feet in an 18 inch by 36 inch tile. 18 inches = 1.5 feet (since there are 12 inches in a foot). 36 inches is 3 feet. The area of a rectangular tile is the width x height, so 1.5 x 3 = 4.5 square feet.
A 24" by 18" tile is 432 square inches or three square feet.
It is not clear what is meant by an "18x18 square feet" tile. 18ft * 18 ft = 324 square feet, so that one tile will be more than enough. An 18 inch by 18 inch tile cannot be a 18x18 square feet tile.

There are 144 18 square inch tiles in an area of 18 square feet.
That depends on the unit of measurement for the tiles. Assuming the tiles are 18 inches by 18 inches, one tile is 324 square inches = 2.25 square feet. Multiply by 106 to get 238.5 square feet. If the tiles are 18 feet by 18 feet (pretty big tiles, but hey, it could happen), one tile is 324 square feet, so 106 pieces of that would be 34344 square feet.
If each tile is 1 1/2 feet by 1 1/2 feet, use the decimal equivalent to do the math: 1.5 x 1.5 = 2.25 square feet.
1 foot = 12 inches Answer = 265/12 x 18/12 = 33.125 sq feet = 34 sq feet tiles
There are 1.5 times 3 = 4.5 square feet in an 18 inch by 36 inch tile. 18 inches = 1.5 feet (since there are 12 inches in a foot). 36 inches is 3 feet. The area of a rectangular tile is the width x height, so 1.5 x 3 = 4.5 square feet.
18 inches is equal to 1.5 feet.Therefore the area is 1.52 = 2.25 square feet.
1.5
There are 2.25 square feet in 1 18" x 18" tile. Counting for NO waste, you would been 71 tile. Since tile this large with surely have some waste you will want to buy around 78 tile.
Multiply the two dimensions to get the area. The calculation will give you 2.25 square feet per tile for a total of 1,305 square feet.
