Answer 2

Hello Dear!!!

Here's your answer....

The length and breadth are in the ratio 6:4

Let,

length is 6x

breadth is 4x

and fencing cost is 80 per meter

the cost is 16,000

now,

16000/80

200

so....200 meters

Now,

perimeter = fencing distance

perimeter = 200

so...

perimeter of rectangle = 2(l+b)

2(l+b) = 200

l+b = 200/2

l+b = 100

6x+4x = 100

10x = 100

x=100/10

x= 10

length = 6x 
           = 6(10)
            = 60

breadth = 4x
              = 4(10)
             = 40

Length is 60m
breadth is 40m
