Question

the floor of a hall is 20 m long and 15 m wide. Find the no. of tiles required to cover the floor if the dimension of one tile is 20cm*10cm

Answer 1

Area =20×15=300m
Dimension of tile is 20×10=200=2m
Therefore number of tiles required is 300÷2=150
So 15000 tiles is required

Answer 2

Hey
______

Area of floor
=( 20×100)×(15×100)=3000000cm^2

Area of tile = 20×10 cm ^2

Req no of tiles = area of floor/area of 1 tile
3000000/200=15000

Hence, ans is 15000
