Let L be 2x
W be x
Circumference 2(2x+x)
Now 5×2(3x)=3000
x=30
Length=60 meters

The length of a rectangular field is twice its width. Ramesh jogged around it 5 times and covered a distance of 3 km.
What is the length of the field?

let width=x then length=2x

perimeter of rectangle=2(length+width)

3km=3000m

3000=5[2(2x+x)]
3000=10*3x
30x=3000
x=100
so length=2*100=200m
