Answer 2

Answer:

Step-by-step explanation: Side of the square park= 420 m

Length to be fenced = perimeter of the square park= 4 × 420

                                                                                         = 1680 m

∴ Cost of fencing = 1680 × 10

                              = 16800 Rs.
