Question
A farmer has a rectangular field having length 230 m and breadth 160 m. He wants to fence it with 3 rounds of rope as shown. What is the total length of rope needed?
Answer

Perimeter of a rectangular field = 2 (length + breadth)
= 2 (230 m + 160 m)
= 780 m
The farmer wants 3 rounds of rope to fence.
Total length of rope needed = 780 m × 3
= 2340 m

Each track is a rectangle. Akshi’s track has length 70 m and breadth 40 m. Running one complete round on this track would cover 220 m, i.e., 2 × (70 + 40) m = 220 m. This is the distance covered by Akshi in one round.
