Answer 2

Answer:

Rs. 24.96 (Rs. 25 approx)

Step-by-step explanation:

Side of Square Ground = 30 m

Length of fencing = Perimeter of Square

                             = 4 × 30 m      [∵ Perimeter of Square = 4 × Side]

                            = 120 m

Cost of erecting 100 m fence  = Rs. 20.80

Cost of erecting 1 m fence       = Rs. 20.80/100

Cost of 120 m Fencing             = (20.80/100) × 120

                                                  = 24.96

∴ Total Cost of erecting fence around the given ground is Rs.24.96
