Question

The length of the rectangular field is twice it’s breadth. Meghna jogged around it 5 times and covered a distance of 3 km. What is the length of the field?

Answer 1

Answer:

0.2km or 200m

Step-by-step explanation:

Let breadth be b

so length would be 2b

now perimeter of the field would be 2(b+2b) = 6b

Meghna jogged 5 rounds so distance covered = 5 × perimeter = 30b

From the question,

30b = 3km

∴ b = 0.1km

length = 2b = 2 × 0.1 = 0.2 km or 200m
