Question

010. A farmer has a rectangular field of length 250 m and breadth 150m. He wants to fence it with 3
rounds of rope. What is the total length of rope he must buy? Also find the total cost if one metre of
rope costs 7.​

Answer 1

Step-by-step explanation:

length of the rope is 2400m.

total cost is 16800

Answer 2

Step-by-step explanation:

length = 250m

breadth = 150m

$perimeter = 2(l + b)$

$perimeter \: = 2 \times 400$

$perimeter \: = 800m$

if , 3 rounds then ,

perimeter = 3 × 800 = 2400m

Therefore , he requires 2400m of rope to fence his field.

$cost \: of \: fencing = 2400 \times 7 \\ \:$

so , the cost of fencing = 16800₹
