A farmer has a rectangular field of length and breadth 240 m and 180 m respectively. Hewants to fence it with 3 rounds of rope. What is the total length of rope he must use?​

Answer»

The farmer has to cover THREE times the perimeter of that field.

Therefore,

Total length of ROPE REQUIRED is thrice its perimeter.

Perimeter of the field = 2 × (length + BREADTH)

Perimeter of the field = 2 × (240 m + 180 m)

Perimeter of the field = 2 × 420 m

Perimeter of the field = 840 m

____________________

Total length of rope required = 3 × 840 m

Total length of rope required = 2520 m
