Question

The length and width of a rectangle field are in the ratio 5 . 1 if its breadth is 60m find the cost of fencing it at Rs 40 per metre .

Answer 1

Answer:

ratio bw length and width = 5:1

so ratio = 5x: x

length = 5x

breadth = x

A2Q, breadth = 60m

so, x = 60

length = 5x = 5*60  = 300 m

now, perimeter = 2 [ l+b ]

perimeter = 2 [ 300 + 60 ]

perimeter = 2 * 360

perimeter = 720 m

1m fencing = rs. 40

720m fencing = rs. 40 * 720

cost of fencing = rs. 2880

hope it helps

have a nice day
