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.
