Answer 1

Length of the rectangular park = 175 m.

Breadth of the rectangular park = 125 m.

Perimeter of park = 2$\times$(length + breadth).

= 2$\times$(175 + 125).

= 2$\times$300 = 600 m.

So, the required fencing for a rectangular park is 600 m.

Since, the cost of fencing park per meter = ₹ 12.

Therefore, the cost of fencing the rectangular park of perimeter 600 m = 12$\times$600 = ₹ 7,200.
