12x12=144 inches

Each tile 9 inches
9 divided into 144=16
9 divided into 180=20; 16 X 20= 320 tiles

If each tile is 9x9 inches sq, then you're right. I approached it
differently.
First I convert the floor area into sq. in.
(12ft)(12 in/ft)(15 ft)(12 in/ft) = 25920 sq in
each tile is 9x9 = 81 sq in
25920/81 = 320 tiles
