Hello

Length of the room = 13 m

Breadth of the room = 9 m
Area of the room = l × b = 13 × 9 = 117 m2

Let the length of the carpet = '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 665

Total cost of the carpet = 156 × 665 = Rs 103,740
