Given side of a square tile = 20cm
Side of a square floor = 3m = 300cm
No.of tiles required to cover the floor = Area of the floor/Area of one tile
Area of floor = 300 × 300 cm²
                     = 90000 cm²
Area of one tile = 20 × 20 cm²
                         = 400 cm²
No.of tiles required to cover the floor = 90000cm²/400cm²
 = 225
∴No.of tiles required to cover the floor = 225
