Answer 2

Four Equations Using Given Area Values

To create four equations using the given area values, we can use the following conversions:

1. 15 cm² can be converted to 0.15 dm² or 1500 mm². 2. 800 dm² can be converted to 80000 cm² or 8 m². 3. 30000 cm² can be converted to 3000 dm² or 0.3 m². 4. 23 m² can be converted to 2300 dm² or 230000 cm².

Using these conversions, we can create the following equations:

1. 15 cm² = 0.15 dm² - This equation represents the conversion of 15 square centimeters to square decimeters. - The conversion factor is 0.01, as 1 square decimeter is equal to 100 square centimeters. - Therefore, 15 square centimeters is equal to 0.15 square decimeters.

2. 800 dm² = 80000 cm² - This equation represents the conversion of 800 square decimeters to square centimeters. - The conversion factor is 100, as 1 square decimeter is equal to 100 square centimeters. - Therefore, 800 square decimeters is equal to 80000 square centimeters.

3. 30000 cm² = 3000 dm² - This equation represents the conversion of 30000 square centimeters to square decimeters. - The conversion factor is 0.1, as 1 square decimeter is equal to 10 square centimeters. - Therefore, 30000 square centimeters is equal to 3000 square decimeters.

4. 23 m² = 230000 cm² - This equation represents the conversion of 23 square meters to square centimeters. - The conversion factor is 10000, as 1 square meter is equal to 10000 square centimeters. - Therefore, 23 square meters is equal to 230000 square centimeters.

These four equations demonstrate the conversions between different units of area using the given values.
