A rectangular floor has dimensions 35 m×20 m. If the floor is tiled with tiles of dimension 25 cm×20 cm, then the number of tiles required is
14,000
Change m to cm by multiplying by 100
⇒3500 cm × 2000 cm
Number of tiles required =Area of floorArea of 1 tile
=3500×200025×20
=14,000
Hence we require 14,000 tiles.
