Answer 1

Answer:

Rs.680

Step-by-step explanation:

Total cost = Rs.1400

Cost of ploughing per m² = Rs.3.50

Hence, area of field = 1400/3.5 m² = 400 m²

Side of square field = √400 m = 20 m

Perimeter = 4×20 m = 80 m

Cost of fencing per meter = Rs.8.50

Total cost of fencing = Rs.8.50×80 = Rs.680
