Question

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

Answer 1

Answer:

3×5=15 =length breadth =15×2=30

Answer 2

Given:

• The length of a rectangular field is twice its breadth.
• A Meghana 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 Meghna jogged along the perimeter of field.

$\\\sf\dashrightarrow 5 \: rounds = 5 × 6 \: x = 30 \: x \: \: m$

$\sf\dashrightarrow 3000 \: m = 30 \: x \: \: m$

$\sf\dashrightarrow x = \frac{3000}{30}$

$\sf\dashrightarrow x = 100 \: m$

${\bigstar{\red{\underline {\boxed {\sf{x = 100 \: m}}}}}}$

hence ,

• Breadth = 100 m
• Breadth = 100 mLength = 2(100) = 200 m
