Answer:

Mr. NARENDRA DAMODAR DAS MODI

Answer 2

Answer:

26400.

Step-by-step explanation:

Given that area of a circular playground is 22176m∧2

Area of circle =πr∧2

∴πr∧2=22176

r∧2=22176/(22/7)

r=$\f\sqrt7056$

∴ Circumference of playground =2πr=2×  22/7×84=528m

Given that, cost of fencing is Rs.50 per meter.

∴ cost of fencing 528 meter =528×50=Rs.26400

Hence, the correct answer is 26400.
