Question

A HALL measures 24m×20m.The number of tiles of size 0.4m×0.3m
required to pave the floor of hall is
1)1500
2)4000
3)3000
4)2500

Answer 1

Area of the floor of hall =24*20=480m^2

Area of 1 tile= 0.3*0.4=0.12m^2

No. of tiles =480/0.12=40*100=4000



Hence, no. Of tiles required to pave the floor is 4000.

Answer 2

4000 tiles is used to pave the floor ...at first find the area of the hall by multiplying the 24m×20m ..and then the answer will be 48000sq.m and then find the area of tiles by..0.4×0.3=0.12 after this 48000÷0.12=4000
