Answer 1

Answer:

Rs.31680

Step-by-step explanation:

Area of circular playground=22176 sq.m

πrr=22176

22/7 ×r square=22176

r square=(22176×7)/22

r square=7056

r =√7056

r=84 m

Circumference of the circular playground=2πr

=2×22/7 ×84

=528 m

Rate=Rs.60/m

Cost of fencing circular playground=528×60

=Rs.31680
