Answer 2

Calculation of Total Grain Yield

To calculate the total amount of grain harvested, we need to determine the yield per hectare for each crop and then multiply it by the total area of the land.

Given information: - Area of land occupied by wheat: 30 hectares - Area of land occupied by barley: 20 hectares - Area of land occupied by corn: 10 hectares - Yield per hectare for wheat: 3 centners - Yield per hectare for barley: 4 centners - Yield per hectare for corn: 2 centners

Let's calculate the total grain yield:

1. Wheat: - Area occupied by wheat: 30 hectares - Yield per hectare for wheat: 3 centners - Total yield of wheat = 30 hectares * 3 centners/hectare = 90 centners

2. Barley: - Area occupied by barley: 20 hectares - Yield per hectare for barley: 4 centners - Total yield of barley = 20 hectares * 4 centners/hectare = 80 centners

3. Corn: - Area occupied by corn: 10 hectares - Yield per hectare for corn: 2 centners - Total yield of corn = 10 hectares * 2 centners/hectare = 20 centners

Now, let's calculate the total grain yield by adding up the yields of wheat, barley, and corn:

Total grain yield = Total yield of wheat + Total yield of barley + Total yield of corn = 90 centners + 80 centners + 20 centners = 190 centners

Therefore, a total of 190 centners of grain were harvested from the given land.
