Question

The length of a rectangular plot of land is twice its breadth. Rohan jogged around it three

times and covered a distance of 3600m. What is the length of this field​

Answer 1

Step-by-step explanation:

Let L and B are the length and breadth of the rectangle.

Given that, L=2B

Perimeters=2×(L+B)

∴ Jamal jogged around it four times and covered a distance of 6 km

∴4×[2×(L+B)]=6 km

⇒4×[2(L+B)]=6 km

⇒8×(L+B)=6 km

⇒8×(2B+B)=6 km

⇒8×3B=6 km

⇒24B=6×1000 m=6000 m

⇒B=

24

6000

m=250 m

∴ The length of the field =2×250 m=500 m.
