Question

Bob wants to cover the floor of a room 3 m wide and 4 m longby squared tiles. If each square tile is of side 0.5 m, then find the number of tiles required to cover the floor of the room.

Answer 1

Area of the floor = side*side =3*4=12`m^2`
Area of the tile = side*side =0.5*0.5=0.25`m^2`
numbers of the tiles required = area of the floor/area of the tile
=12/0.25= 48 tiles.
