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

Answer:

A farmer has a rectangular field of length and breadth 240 m and 180 m respectively. He wants to fence it with 3 rounds of rope as shown in figure 10.4. What is the total length of rope he must use? =2520m

Step-by-step explanation:

Perimeter of rectangular field = 2(l+b)

= 2×420

=840m

the perimeter of the rectangular field is 840m. so, farm need 840m long rope to fence the field 1 time.

total rope need to fence the field 3 times=840×3=2520m
