б)100000мм² - 10000см²

в) 45га - 4500а - 450000000000мм²

Answer 2

To convert these units, we need to use the appropriate conversion factors:

1 hectare (ha) = 10,000 square meters (m²) 1 square meter (m²) = 10,000 square centimeters (cm²) 1 square meter (m²) = 1,000,000 square millimeters (mm²)

Let's start with the first conversion:

1. 3 hectares (ha) to square centimeters (cm²):

1 ha = 10,000 m² (conversion factor) 3 ha * 10,000 m² = 30,000 m²

Now, we convert square meters to square centimeters:

30,000 m² = 30,000 * 10,000 cm² (conversion factor) 30,000 * 10,000 = 300,000,000 cm²

So, 3 hectares is equal to 300,000,000 square centimeters.

Next, let's convert 1,000,000 square millimeters (mm²) to square centimeters (cm²):

2. 1,000,000 square millimeters (mm²) to square centimeters (cm²):

1 m² = 1,000,000 mm² (conversion factor) 1,000,000 mm² = 1,000,000 / 10,000 cm² (dividing by 10,000 to convert to cm²) 1,000,000 / 10,000 = 100 cm²

So, 1,000,000 square millimeters is equal to 100 square centimeters.

Finally, let's convert 45 hectares (ha) to square millimeters (mm²):

3. 45 hectares (ha) to square millimeters (mm²):

1 ha = 10,000 m² (conversion factor) 45 ha * 10,000 m² = 450,000 m²

Now, we convert square meters to square millimeters:

450,000 m² = 450,000 * 1,000,000 mm² (conversion factor) 450,000 * 1,000,000 = 450,000,000,000 mm²

So, 45 hectares is equal to 450,000,000,000 square millimeters.
