For given question,
A farmer can plant 45 kg of peanuts on 4,000 square meters of land.
Using unitary method,
This means, a farmer can plant 1 kg of peanuts on 88.89 square meters of land.
We need to find the number of peanuts ( x ) he could plant on 8,500 square meters of land.
Here, 1 kg = 88.89 square meters
x kg = 8500 square meters
Therefore, the number of peanuts ( x ) he could plant on 8,500 square meters of land = 95.6 kg
