Question

the length of a rectangular field is twice its breadth. Meghna jogged around its 5 times and covered a distance of 3 km. what is the length of the field?​

Answer 1

Answer:

200 m

Step-by-step explanation:

Dude its very easy...just follow my steps

Let the breadth be 'b' km

Hence, length = 2 x b km

Now as she is jogging 'around' the field, we will consider the perimeter not the area,

So,

Perimeter = 2 x (l + b) km

= 2 x (2b + b) km

= 6b km

now,

She jogged 5 times so, 5xperimeter

A.T.P.

=) 5 x 6b = 3

=) b = 3 / 30

=) b = 0.1

Thus,

Breadth = 0.1 km = 100 m

Length = 2 x 0.1 km = 200 m

Hope it helps you buddy....
