Given l =2b
Given man jogged 5times around it and covered = 3KM = 3000m
That is 5times × Perimeter = 3000m
5 ( 2(l +b)) =3000
2(l + b) = 600
l + b = 300
3b = 300
b= 100m
l = 200m

Answer:length = 200m
Step-by-step explanation:
Perimeter of the rectangular field = 300m/5
=600m
600=2(l+b)
300=l+b
l=2b
3b=300
b=100
l=200
