The cost of levelling and turfing a square field at Rs. 160 per hectar...
Area of the square field in hectares=total cost/cost per hectare=2624.40/160=16.4025 ha
1 hectare =1000 m2
∴ area of square field=164025 m2
side of square field=a=√164025=405 m
total cost of surrounding the field with railing=perimeter of field × cost of railing per metre=4 × a × .25= Rs.405

The cost of levelling and turfing a square field at Rs. 160 per hectar...
Given data:
Cost of levelling and turfing a square field = Rs. 2624.40
Cost per hectare = Rs. 160
Cost per square meter = 160/10000 = Rs. 0.016
To find:
Cost of surrounding the field with a railing costing 25 paise per meter.
Solution:
Let the side of the square field be 'a' meters.
Area of the square field = a^2 square meters
Cost of levelling and turfing the field = Rs. 2624.40
Cost per square meter = Rs. 0.016
Cost of levelling and turfing the field = Area of the field × Cost per square meter
2624.40 = a^2 × 0.016
a^2 = 164025
a = 405
The perimeter of the square field = 4a = 1620 meters
Cost of railing per meter = 25 paise = 0.25/100 = Rs. 0.0025
Total cost of railing = Perimeter of the field × Cost of railing per meter
= 1620 × 0.0025
= Rs. 4.05
Hence, the cost of surrounding the field with a railing is Rs. 4.05, which is closest to option D (Rs. 405).
Cost of levelling and turfing a square field = Rs. 2624.40
Cost per hectare = Rs. 160
Cost per square meter = 160/10000 = Rs. 0.016
To find:
Cost of surrounding the field with a railing costing 25 paise per meter.
Solution:
Let the side of the square field be 'a' meters.
Area of the square field = a^2 square meters
Cost of levelling and turfing the field = Rs. 2624.40
Cost per square meter = Rs. 0.016
Cost of levelling and turfing the field = Area of the field × Cost per square meter
2624.40 = a^2 × 0.016
a^2 = 164025
a = 405
The perimeter of the square field = 4a = 1620 meters
Cost of railing per meter = 25 paise = 0.25/100 = Rs. 0.0025
Total cost of railing = Perimeter of the field × Cost of railing per meter
= 1620 × 0.0025
= Rs. 4.05
Hence, the cost of surrounding the field with a railing is Rs. 4.05, which is closest to option D (Rs. 405).
