Question

a room is 13m long and 9M broad find the cost of carpeting the room with a carpet 75cm broad @ rupees 65 per metre​

Answer 1

Given: length = 13m

Given: breadth = 9m

Area of the room = length × breadth

= 13m × 9m = 117m

= 11,700cm

Breadth of one carpet = 75cm

Area of the room = 117m = 11,700cm

Carpets required = 11,700 ÷ 75 = 156

Breadth of 156 carpet = 11,500cm

Cost of 100cm carpet = Rs 65

Cost of 1cm carpet = Rs 65/100 11,500cm carpet costs = 65/100×11500

= Rs 7, 605

Therefore the total cost of the carpet is Rs seven thousand six hundred five.

Hope it helps.
