Expected number of yam plants = Number of planting spots per hectare * Total area of the farmland
Expected number of yam plants = 10,000 * 1.5 = 15,000
Therefore, the expected number of yam plants on the 1.5 hectares of farmland would be 15,000 plants.
4cii.
Total weight = Expected number of yam plants * Average weight of each yam tuber
Total weight = 15,000 * 3.5 kg = 52,500 kg
Therefore, the total weight of the yam tubers harvested on the 1.5 hectares of farmland would be 52,500 kilograms (or 52.5 metric tons).
