Answer 2

Answer:

The length = 200m

Step-by-step explanation:

let breadth be = x

and length be = 2x( in the question length is twice the breadt mentioned)

Now,

Meghna jogged 5times = covered distance 3km

then 1 time = ?

Perimeter of Rectangle = 2(l+b)

1 time => 2(x+2x)=6x meters

5 times =>5×6x meters

( 3km = 3000 meters )

3000m = 30x meters

x= 3000/30

x= 100 meters

now length =2.x meters

=2×100

= 200 meters

• length = 200 meters
• breadth = 100 meters
