Question

A hall id 20m long and 18m broad , a carpet is to be laid in this hall leaving a margin of 1m all around . Find :
1. The lenght and the breadth of the carpet required.

2. The area of the carpet and its cost at the rate of 150 per m ²​

Answer 1

Step-by-step explanation:

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.
