Area of the floor= 20*5= 100m^2
Area of square tiles= side*side
= 20*20=400cm
Therefore no of tiles needed=
100*10000/400
=2500Tiles (Ans).

Area of floor = 5m×20m = 500cm × 2000cm
Area of square tiles = (20cm)² = 400cm²
Number of tiles needed = Area of floor / Area of tiles
=500×2000/400= 10000/4 = 2500 tiles
Area of square tiles = (20cm)² = 400cm²
Number of tiles needed = Area of floor / Area of tiles
=500×2000/400= 10000/4 = 2500 tiles
