Option 3 : Rs. 5154

**Given:**

Length of wire 1 = 58 m

Length of wire 2 = 86 m

The cost of plowing = Rs. 4 per m2

**Formula Used:**

Perimeter of square = 4 × Side

Area of the square = Side^{2}

**Calculation:**

Total length of wire = 58 + 86 = 144 m

Perimeter of square field = 4 × Side

⇒ Perimeter of square field = Total length of wire

⇒ 124 m = 4 × Side

⇒ Side = 36 m

Area of the square field = Side2

⇒ 36^{2} = 1296 m^{2}

The cost of plowing = 4 × 1296 = Rs. 5184

**∴ The cost of plowing square field is Rs. 5184**
