In practice you will use more tiles than the equivalent area of the room. A 15 foot strip of tiles will require 15 times 12/13 = 13.846 tiles to cover it. This will have to be rounded to 14 tiles. That means that the 15 foot by 15 foot room will require 14 times 14 tiles = 196 tiles to cover it. And that's if you don't drop and break any or mess up one or more cuts.
15 x 15 = 225 square feet
30 X 15 = 450 square feet.
A 19' x 15' room is 285 square feet or 26.477 square meters.
165 square feet

150/400 is one possible answer.
There are 270 square feet in a 15'x18' room.
The floor and ceiling are each (28 x 15) = 420square feet.We don't know the area of the walls until we know how high the room is.
15/100 = 30/200 = 60/400
I just went to the tree store today and they quoted me $400 for a 15 foot shade tree with a 4 inch diameter trunk (at base).
15 x 20 = 300 square feet.
Assuming the tiles are 1 foot squares, you would need 10*15 = 150 tiles.
