Question

The length of a rectangular field is twice it's breadth. Meghna jogged around it 5 times and cover a distance of 3 km.What is the length of the field.​

Answer 1

Answer:

let the breadth of the rectangular field be x

and the length of the rectangular field be 2x

in 5 round ,Meghna jogged= 3km=3000m

in 1 round Meghna jogged=3000m/5

=600m

=perimeter of rectangular field=600m

=2(2x+x)=600m

=2(3x)=600m

=6x=600m

=x=600m/6

=x=100m

therefore,the breadth of the rectangular field is

x=100m

and the length of the rectangular field is

2x=2(100)m=200m
