This is your required answer. Thanks for asking.

Answer 2

Answer:

Given that :-

The length of a rectangular field is twice its breadth.

A man jogged around it 5 times and  covered a distance of 3 km.

To find :-

Length of the field

Solution :-

Let breadth of field be x m.

length of field = 2x m

A man jogged along the perimeter of field.

⇒ 5 rounds = 5 × 6x = 30x m

⇒ 3000 m = 30x m

⇒ x = 3000/30

⇒ x = 100 m

Breadth = 100 m

Length = 2(100) = 200 m .
