Let the side of square field be x
Cost of levelling the field per m² = ₹15
Total cost of levelling the field = ₹19,935
Therefore, According to the given question,
15x² = 19935
=> x² = 1329
=> x = 36.45 approx.
Cost of fencing the field per m = ₹22
Therefore, Fencing cost = 22*36.45*4 = ₹3208 approx.
