Question

The length of a rectangular field is twice the breadth. A man ran around 5 times covering 3 km. What is the length then?

Answer 1

Step-by-step explanation:

let the breadth be x

so,length 2x.

As the man ran 5 time and covered 3km=3000m

perimeter =3000/5=600m.

2(l+b)=600

2(2x+x)=600

6x=600

x=100

l=2x=2*100=200m or 0.2km
