Question

Aruna wants to cover floor of a room which is 3 m wide and 4 m long by square tiles. if each square tile is of side 20cm, find the number of tiles required to cover the floor of the room​

Answer 1

Answer:

Aruna  require 300 tiles to cover the floor.

Step-by-step explanation:

Length of floor = 4 metres

breadth of the floor = 3 metres

Area of the floor = 4m ×3m = 12 sq. m

Length of the tile = 20cm=0.2 m

Area of the tile = 0.2 ×0.2 = 0.04 sq. m

Number of tiles required =$\frac{12}{0.04} =300$
