Question

The length of a rectangular field is twice its breadth.A girl jogged around it 4 times and covered a distance of 4.5 km . what is the length of the field?​

Answer 1

Answer:

Hey frnd here is ur answer

375 m or 0.375 km

Step-by-step explanation:

Let the length of field be '2x'. So the breadth will be x.

Perimeter of the ground(distance covered in 1 round)= 2(l+b)

=2(2x+x)

=6x

Distance covered in 4 rounds= 4*(6x)

=24x

since it is given 4.5 km or 4500m

24x=4500 m

x=4500/24

x=187.5 m

Since the length=2x

l= 2*187.5m

l=375 m or 0.375 km.
