Answer:

Define area of a plane closed figure. The length and breadth of a room are 6 meter and 5 meter respectively. How many square meters of carpet costs rupees 240 per square meter how much will it cost to cover the entire room

Step-by-step explanation:

Length of the room = 13 m

Breadth of the room = 9 m

Area of the room = l × b = 13 × 9 = 117 sq m

Let the length of the carpet required = 'l' m

Width of the carpet = 75 cm = 0.75 m

Area of the carpet = Area of the room

⇒ l × 0.75 = 117

⇒ l = 117 / 0.75

⇒ l = 156 m

Length of the carpet required = 156 m

Cost of the carpet per metre = Rs 105

Total cost of the carpet = 156 × 105 = Rs 16380.
