The Area of the ground = 22176 m²

Area of the circle = πr²

⇒ πr² = 22176

⇒ r² = 22176 × 7/22

⇒ r² = 1008×7 = 7056 m²

⇒ r = √ 7056

Perimeter = 2πr = 2

Cost = 508 / 50 = Rs 10.16

Hence the cost for building the fence is Rs 10.16

I hope th4 answer is correct !

Please mark this answer as the best !
