To find the cost of manuring the farm, we first need to find the area of the farm in hectares.

The area of the farm is given by the formula:

Area = Length × Width

Converting the dimensions to hectares:

Length = 380 m = 380/100 = 3.8 hectares Width = 100 m = 100/100 = 1 hectare

Area = 3.8 hectares × 1 hectare = 3.8 hectares

Next, we need to find the total amount of manure required for the farm. It is given that 2 quintals of manure has to be applied per hectare.

Total manure required = 2 quintals/hectare × 3.8 hectares = 7.6 quintals

Finally, we can find the cost of manuring the farm by multiplying the total manure required by the cost per quintal.

Cost = Total manure required × Cost per quintal = 7.6 quintals × ₹450.00/quintal = ₹3420.00

Therefore, the cost of manuring the farm is ₹3420.00.
