@Vaitheeswaran How can a playgorund be in mm, obviuosly it has to be in meters or cms... but i suppose its "80 metres"...
Cost should be "Rs 150 per meter" as fencing can only be done around a ground and not over the ground, so here comes "circumference" into play.
and the answer is:
(rate per metre)* pi * diameter= 150 * 22/7 * 70
= Rs 33000
