Area of each tile = 13*13 = 169 sq inches.
Area to be cover = 12*12 sq ft = 20,736 sq inches.
So minimum number of tiles required = 20,736/169 = 122.7 = 123 tiles.
However, this assumes that the shape is well behaved and that all offcuts can be used. In real life, you should allow 5% more tiles for wastage.
