Best answer

Length of rectangular park (l) = 175 cm

Breadth of rectangular park (b) = 125 cm

Length of wire required for fencing the park =

Perimeter of the park

= 2 × (l + b)

= 2 × (175 + 125)

= 2 × 300 = 600 m

Cost for fencing 1 m of the park = Rs 12.

Cost for fencing 600 m of the square park = 600 × 12

= Rs. 7200
