Perimeter of Rectangle ⇒ 2 (Length + Breadth)

Length ⇒ 175 m

Breadth ⇒ 125 m

Perimeter of Rectangle ⇒ 2 (175 + 125)

Perimeter of Rectangle ⇒ 2 (300)

Perimeter of Rectangle ⇒ 600

∴ Perimeter of Rectangular park is 600 m

Cost of fencing at the rate of ₹12 per metre.

Cost of fencing ⇒ Perimeter × Cost of fencing per metre

Perimeter ⇒ 600 m

Cost of fencing per meter ⇒ ₹12

Cost of fencing ⇒ 600 × 12

Cost of fencing ⇒ ₹7200

∴ The cost of fencing a rectangular park of length 175 m and breadth 125 m at the rate of ₹12 per metre is ₹7200
