Answer :

Area of the circular playground = 22176 m2 (Given)


Let r be the radius of the circle.


πr2 = 22176


(22/7)r2 = 22176


r2 = 22176 × (22/7)


r2 = 7056


r = 84


Radius of the circular playground = 84 m


Now, circumference of the circle = 2πr


= 2×(22/7)×84


= 528 m


Cost of fencing 1 meter of ground = Rs 50


Cost of fencing the total ground = Rs 528 × 50 = Rs 26,400
