Question

A room is 13 m long and 9 m broad. Find the cost of carpeting the room with a carpet
75 cm broad at 50 per metre.​

Answer 1

Answer:

Length of the room = 13 m

Breadth of the room = 9 m

Area of the room = (139) m2 = 117 m2

Let length of required carpet be x m.

Breadth of the carpet = 75 cm

= 0.75 m (100 cm = 1 m)

Area of the carpet = (0.75x) m2

= 0.75x m2

For carpeting the room:

Area covered by the carpet = Area of the room

So, the length of the carpet is 156 m.

Cost of 1 m carpet = Rs 65

Cost 156 m carpet = Rs (15665)

= Rs 10140

13m long and 9m broad 13×9=117 m 117×50=5850 75cm=0.75 m 5850×0.75=4387.5 m ans
