In case of floor
Lenght=14m=1400 cm
breadth = 25/2m=1250cm
In case of tile
length = 10cm
breadth = 7cm
no.of tiles required = area of floor/area of tile
=1400×1250/10×7
=25000
so 25000 tiles are required

l of tile=10 cm
b of tile =7cm
area of tile =10cm*7cm
=70cm^2
=0.7m^2
l of floor=14m
b of floor=25/2 m
area of floor=14m*25/2m
=175m^2
cost of 100 tile=rs 5
cost of full floor=(0.7m^2*175m^2)*rs 5
=122.5m^2*rs 5
=rs 612.5
b of tile =7cm
area of tile =10cm*7cm
=70cm^2
=0.7m^2
l of floor=14m
b of floor=25/2 m
area of floor=14m*25/2m
=175m^2
cost of 100 tile=rs 5

=122.5m^2*rs 5
=rs 612.5
