If the seed rate for the cultivation of cowpea is 25 kg per hectare, determine the quantity of cowpea seeds required to cultivate a farmland measuring 100 m by 500 m.
1 hectare = 10,000 square meters
Area of the farmland = 100 m x 500 m = 50,000 square meters
Now, we can convert the area to hectares:
Area in hectares = 50,000 square meters / 10,000 square meters/hectare = 5 hectares
Next, we can calculate the quantity of cowpea seeds required using the given seed rate:
Seed rate = 25 kg/hectare
Quantity of cowpea seeds required = Seed rate x Area
Quantity of cowpea seeds required = 25 kg/hectare x 5 hectares
Quantity of cowpea seeds required = 125 kg
Therefore, the quantity of cowpea seeds required to cultivate the farmland is 125 kg. The correct answer is "125 kg."
