You can put this solution on YOUR website!
length of the room = 20 meters.
width of the room = 18 meters.

you want a margin of 1 meter around the carpet.
you have to subtract 1 meter from both sides of the length of the room to get:
length of the carpet = 20 - 2 = 18 meters.
you have to subtract 1 meter from both sides of the width of the room to get:
width of the carpet = 18 - 2 = 16 meters.

area of the carpet is 18 * 16 = 288 square meters.

at a cost of 150 rupees for each square foot, the total cost would be equal to:
150 * 288 = 43,200 rupees.
