Question

A square room having one side equal to 12 m is to be paved with a square tiles of 50 cm.what is the number of tiles required to pave the room

Answer 1

no of tiles=area of room/area of 1 tile
area of room =(1200X1200)cm
=1440000cm^2
area of 1 tile =(50X50)cm
=2500cm^2
no of tile=1440000/2500
=576 tile.

Answer 2

Area of floor=12×12=144sq m

Side of tile=50cm=0.5m
Area of tile=0.5×0.5=0.25sq m

So tiles needed for this room=144/0.25
=576 tiles are needed
