Find the cost of carpeting a room 13 m long and 9 m broad with a carpet 75 cm wide at the rate of ₹12.40 per square metre. (M.B.A., 2011)
Answer
Answer (as printed):
Explanation
Area of the carpet = Area of the room $=(13 \times 9)\text{ m}^{2}=117\text{ m}^{2}$. Length of the carpet $=\left(\frac{\text{Area}}{\text{Width}}\right)=\left(117 \times \frac{4}{3}\right)\text{ m}=156\text{ m}$. ∴ Cost of carpeting $=₹(156 \times 12.40)=₹1934.40$.
