if i have a 90 length and a 40 width inch of a house and i want to add tiles so i get a 16 inch by 16 inch tile for a "perfect square" how may tiles will i need
If you tile a 5x2 section, you cover 80x32 inches.
That leaves an 8x90 strip across the top, which uses up another 3 tiles
That leaves a 10x32 strip on the left, which uses 2 more tiles
Total: 15 tiles
