Answer:
Firstly we have to find the area of floor
Length of floor=15m
Breadth of floor=12m
Area of floor=l*b
= 15*12
=180m
Area of floor in cm=180*100
=18000cm
Length of barbil tile=45cm
Breadth of barbil tile=20cm
Area of tile=45*20
= 900
No. of tiles required = Area of floor/Area of tile
=18000/900
=20
So number of tiles required for floor is 20
