₹2.5 = 1 m²

₹13322.5 = (13322.5/2.5) m²

Area of square = 5329 m²

Area of square = 5329 m²

Side of square = √5329 m

Side of square = 73 m

Perimeter of square = 4 × Side

Perimeter of square = 4 × 73

Perimeter of square = 292m

Cost of fencing 1 m = ₹5

Cost of fencing 292 m = ₹(292×5)

Cost of fencing 292 m = ₹1460
