₹15 = 1 m²

₹19935 = (19935/15) m²

Area of square = 1329 m²

Area of square = 1329 m²

Side of square = √1329 m

Side of square = 36.4 m

Perimeter of square = 4 × Side

Perimeter of square = 4 × 36.4

Perimeter of square = 145.6 m

Cost of fencing 1 m = ₹12

• Cost of fencing 145.6 m = ₹(145.6 × 12)

Cost of fencing 145.6 m = ₹1747.2
