C Correct answer
Explanation

The side of the square park is sqrt(506.25) = 22.5 m. The perimeter is 4 * 22.5 = 90 m. The cost of fencing is 90 * 30 = Rs. 2700.

AI explanation

The area of the square park is 506.25 square meters, so taking the square root gives a side length of 22.5 meters. The perimeter of a square is four times the side length, giving a total boundary of 90 meters. Multiplying this perimeter by the fencing cost of Rs. 30 per meter results in a total cost of Rs. 2700.
