Answer»

Let the width of the room be 'b' m

Length of the room = 15 m

Area of the room = 15 × b = 15b m2

Total cost of carpeting = Rs 19200

Cost of carpet per metre = Rs 80

Length of the carpet = 19200 / 80 = 240 m

Width of the carpet = 75 cm = 0.75 m

Area of the carpet = 240 x 0.75

Area of the room = Area of the carpet

⇒15b = 240 × 0.75

⇒ b = (240 × 0.75) / 15 = 12

Therefore, width of the room is 12 m.
