Answer 2

To calculate the given expressions, let's convert the units and perform the calculations:

1. 2 cm² - 1000 mm²: Since 1 cm = 10 mm, we can convert cm² to mm² by multiplying by 100 (10 * 10): 2 cm² = 2 * 100 mm² = 200 mm²

   Now we can subtract 1000 mm² from 200 mm²: 200 mm² - 1000 mm² = -800 mm²

   Therefore, 2 cm² - 1000 mm² equals -800 mm².

2. 4 m² - 1000 dm²: Since 1 m = 10 dm, we can convert m² to dm² by multiplying by 100 (10 * 10): 4 m² = 4 * 100 dm² = 400 dm²

   Now we can subtract 1000 dm² from 400 dm²: 400 dm² - 1000 dm² = -600 dm²

   Therefore, 4 m² - 1000 dm² equals -600 dm².

3. 2 ha - 10000 m²: Since 1 ha = 10000 m², we don't need to convert the units: 2 ha - 10000 m² = 20000 m² - 10000 m² = 10000 m²

   Therefore, 2 ha - 10000 m² equals 10000 m².

4. 100 m² + 2 ha: Again, since 1 ha = 10000 m², we don't need to convert the units: 100 m² + 2 ha = 100 m² + 2 * 10000 m² = 100 m² + 20000 m² = 20100 m²

   Therefore, 100 m² + 2 ha equals 20100 m².

5. 3 dm² - 1000 cm²: Since 1 dm = 10 cm, we can convert dm² to cm² by multiplying by 100 (10 * 10): 3 dm² = 3 * 100 cm² = 300 cm²

   Now we can subtract 1000 cm² from 300 cm²: 300 cm² - 1000 cm² = -700 cm²

   Therefore, 3 dm² - 1000 cm² equals -700 cm².

6. 1 a - 100 m²: Since 1 a = 100 m², we don't need to convert the units: 1 a - 100 m² = 100 m² - 100 m² = 0 m²

   Therefore, 1 a - 100 m² equals 0 m².

7. 3 ha - 10000 m²: Since 1 ha = 10000 m², we don't need to convert the units: 3 ha - 10000 m² = 30000 m² - 10000 m² = 20000 m²

   Therefore, 3 ha - 10000 m² equals 20000 m².

Please note that negative results indicate a difference in magnitude between the two quantities, and the units are maintained in the results.
