Question

A marble tile measures 15 cm× 20 cm. How many tiles will be required to cover a wall of size 4m ×6m?

​

Answer 1

Area of a tile = lenght✖️ breadth
= 15✖️20
= 300cm

Area of wall =lenght✖️breadth
= 4✖️6
=24m
1m=100cm
Therefore, 24✖️100=2400cm


Total number of tiles require=area of wall➗area of tile
= 2400➗300
=8
Therefore 8 tiles needed to cover the wall.
