Question

A room is 15m long and 9m broad. find the cost of carpeting the room with a carpet 75cm broad at the rate of ₹10 per metre​

Answer 1

Step-by-step explanation:

Perimeter of room

as the 2 sides are not equal so it must be a rectangle and f 2 * l+b so

2 * [ 13 + 9 ]

44 m

cost per 75 cm. = 65

therefore cost of carpet = 1 m = 100 cm so

44 m = 44 * 100 cm

4400 cm.

4400 cm. * 10 = 44000 answer cost of room
