Find the cost of carpeting a room 13 m long and 9 m broad with a carpet 75 cm wide at the rate of Rs. 12.40 per square metre. 

Answer»

Area of the carpet = Area of the room = (13 * 9) m2 = 117 m2 . 

Length of the carpet = (area/width) = 117 *(4/3) m = 156 m. 

Therefore Cost of carpeting = Rs. (156 * 12.40) = Rs. 1934.40.
