Question

A room 4.9 M long and 3.5 M broad is covered with carpet leaving and uncovered margin of 25 CM around the room. if the breadth of the carpet is 80 cm, find its cost at rupees 40 per metre

Answer 1

Area of carpet = (4.9 – 0.5)(3.5 – 0.5) m2 = 4.4 * 3.0 = 13.2 m2

Length of the carpet = 13.20.80m = 16.5m

Cost of carpet = Rs. 40 per metre

Cost of 16.5 m carpet = Rs. (40 * 16.5) = Rs. 660
