Question

the length of a rectangular field is twice its breadth Meghna joint around it 5 times and cover a distance of 3 kilometre what is the length of field

Answer 1

here is your answer...

Answer 2

Let the breadth be x
Then length = 2x

Given, she joint around it 5 times and cover distance of 3km. It means :-

5(Perimeter) = 3000 m
5 [ 2(l+b) ] = 3000m
2(2x + x) = 3000/5
2(3x) = 600
3x = 300
x = 300/3
x = 100m

Breadth = x = 100m
Length = 2x
= 2(100) = 200m
