Question

13. A room is 13 m long and 9 m broad. Find the cost of carpeting the room with a carpet 75cm broad at ₹50 per metre.
​

Answer 1

Answer:

₹7800

Step-by-step explanation:

length of room = 13m

breadth of room = 9m

so, area of room = length×breadth

= 13×9 = 117 m

length of carpet = x

breadth of carpet = 75cm = 0.75m

so area of carpet = 0.75x cm

we know that area of carpet = area of room

= 0.75x = 117

= x = 117/0.75

= x = 156m

so, length of carpet = 156m

cost of carpeting = ₹50/m

so total cost = 50×156 = ₹7800

therefore, total cost of carpeting= ₹7800
