Answer: 500 tiles
Step-by-step explanation:
Given - Area of the floor = 2800m ( square)
Height of the tile = 20 cm
Base of the tile = 28 cm
Area of the tile = base x height (parallelogram)
= 28 x 20
= 560
Therefore area of a tile is 560sq. cm
1m = 100cm
2800m = 280000sq.cm
No. Of tiles required
= area of floor / area of tile
= 280000 / 560
= 500
Therefore 500 tiles are required.
