Step-by-step explanation:

Answer 2

1 round length of rope = circle's perimeter

perimeter = π×d

= 22×21

7

= 22×3

= 66m

66m = one round of rope

66×2 = 2 round of rope

132m = 2 round of rope

1m rope cost = ₹4

132m rope cost = ₹4×132

= ₹528

the length of 2 round of rope is 132m.

the cost of 2 round fencing is ₹528.
