Hello,
First, we need to change the measurements to inches which will be:
152 inches wide and 225 inches long. Now multiply these and we get:
34200 square inches Since the tiles are 8 inch squares, that would be one tile has 64 square inches.Then we divide 64 into 34200. This comes up with:
534.375 We therefore need:
535 tiles
