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
