Question

A room is18 metre long and 10 metre wide find the cost of carpeting the floor with 75 cm wide at rupees 16 per metre​

Answer 1

Step-by-step explanation:

Given

the length of room=18m

the wide of room=10m

so,

Area of room=l*b

=18*10=>180m^2

here

carpeting the floor with 75cm

thus

length of carpet=18-1.5=>16.5

wide of carpet=10-1.5=>8.5

the area of carpet=16.5*8.5=>140.25m^2

now:-

the area of carpeting floor=180-140.25

=39.75m^2

hence:-

the cost of carpeting floor=39.75*16

=₹636
