Expert Answer
The cost of fencing a square filed = 16 per metre
Cost of fencing = Rs. 32000
Perimeter of a field = 32000/16 = 2000 m
4x = 2000
x = 500 m where x is the side of a square filed.
Area of square = 5002 = 250000 m2
Rate of reaping a field = 100 per m2
cost = 250000 × 100
cost = Rs. 25000000
