Question

6. Find the cost of carpeting a room 13 m by 9 m with a carpet of width 75 cm at the rate of
105 per metre.​

Answer 1

Answer:

$answer$

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 required = 'I' m

width of the carpet = 75 cm = 0.75 m

area of the carpet = area of the room

=> l × 0.75 = 117

=> 1 = 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
