Answer 1

length of floor=4m
Breadth of floor=3m
 Area of floor=4*3=12m

side of tile=0.5m
Area of tile=0.5*0.5=0.25m

tiles required= area of floor/area of tile
                     =12/0.25
                     =48 tiles

Answer 2

the perimeter of the floor=2×(3+4)
=14

perimeter of a square tile=0.5×4
=2

therefore, =14÷2
=7
ans.7 tiles are required to cover the floor.
