Answer 1

$\huge\sf\underline{Answer}$

Perimeter of Square Field = Total Cost/Rate of Fencing

4 × Side Length = 32000/16

4 × Side Length = 2000

Hence side of length = 500 m.

Now, area of sqare field = (side length)²

= (500)³

= 250000 m²

Cost of reaping field = Rate of Reaping × Area of Sqare Field.

= 35/100 × 250000

= 35 × 2500 = ₹ 87500
