. A room is 20 m long and 18 m broad. Find the cost of carpeting the room with a carpet of width 1.5 m at the rate of Rs. 60 per metre​

Answer 1

Answer:

Step-by-step explanation:

Cost of the carpeting is ₹ 14400 .

Formula

Area of the rectangle = Length × Breadth

As given

A room is 20m long and 18m broad.

Carpet of width 1.5m at the rate of ₹ 60 per metre .

Thus

Area of the room = 20 × 18

= 360 m²

As breadth of the carpet = 1.5 m

Thus

Length of the carpet × Breadth of the carpet = Area of the room

Length of the carpet × 1.5 = 360

Length\ of\ the\ carpet = \frac{360}{1.5}Length of the carpet=

1.5

360

​

Length of the carpet = 240 m

Thus

Cost of the carpeting = Length of the carpet × Cost per meter

= 240 × 60

= ₹ 14400

there fore the cost of carpet is 14400₹.
