Question

find the cost of covering a floor 8.4 by 5.5 metre with a carpet 7DM wide at the rate of Rs 9.0 per metre.​

Answer 1

Step-by-step explanation:

length of the floor = 8.4 m

breadth of the floor = 5.5 m

area of floor = l × b

= 8.4 × 5.5

= 46.20 sq m

width of carpet = 7 dm = 0.7 m

let the length be l

area to be covered = 46.20 sq m

l × 0.7 = 46.20

l = 46.20/0.7

l = 66 m

required carpet

= 66 × 0.7

= 46.20 sq m

rate of carpet Rs. 9 per meter

= 46.20 × 9

= 415.80

total cost of carpet = Rs. 415.80
