The length of a rectangular field is twice its breadth. Jamal jogged around it four times and covered a distance of 6km. What is the length of the field?

Question

Philoid · Accepted Answer

Given:

length, l = 2 × breadth, b

Distance covered after 4 times of jogging = 6 km

Perimeter of field = 6 / 4

= 1.5 km or 1500 m

Perimeter = 2 × (l + b)

2 × (l + b) = 1500

2 × (2b + b) = 1500

2 × 3b = 1500

6b = 1500

b = 250 m

Length, l = 2 × 250

Length = 500 m
