If the recommended seed rate of maize is 20 kg per hectare, calculate the amount of seeds required for 1.8 hectares of farmland.

Answer Details

If the recommended seed rate of maize is 20 kg per hectare, then for 1 hectare of farmland, the amount of seeds required is 20 kg. To calculate the amount of seeds required for 1.8 hectares of farmland, we can use a simple proportion: 20 kg is to 1 hectare as X kg is to 1.8 hectares This can be expressed as: 20/1 = X/1.8 To solve for X, we can cross-multiply: 20 × 1.8 = X × 1 36 = X Therefore, the amount of seeds required for 1.8 hectares of farmland is 36 kg. In summary, if the recommended seed rate of maize is 20 kg per hectare, then 36 kg of seeds are required for 1.8 hectares of farmland.
