Let's convert the area measurements into millimeters squared (mm²), centimeters squared (cm²), and decimeters squared (dm²) for you! 1. **Starting with the first conversion:** - \(2.5 \, \text{cm}^2\) = \(2.5 \, \text{cm}^2\) (it's already in cm²) - To convert to mm², remember that \(1 \, \text{cm} = 10 \, \text{mm}\) so, \[ 2.5 \, \text{cm}^2 = 2.5 \times 100 = 250 \, \text{mm}^2 \] 2. **Second part:** - \(2.05 \, \text{dm}^2\) = \(2.05 \, \text{dm}^2\) (already in dm²) - To convert to cm², \(1 \, \text{dm} = 10 \, \text{cm}\) hence, \[ 2.05 \, \text{dm}^2 = 2.05 \times 100 = 205 \, \text{cm}^2 \] - For mm², it will be \(205 \, \text{cm}^2 = 205 \times 100 = 20500 \, \text{mm}^2\) 3. **Lastly:** - \(20.5 \, \text{m}^2\) = \(20.5 \, \text{m}^2\) (already in m²) - To convert to cm², \(1 \, \text{m} = 100 \, \text{cm}\), \[ 20.5 \, \text{m}^2 = 20.5 \times 10,000 = 205000 \, \text{cm}^2 \] - For mm², it can be converted as follows: \(20.5 \, \text{m}^2 = 20.5 \times 1,000,000 = 20500000 \, \text{mm}^2\) So, in summary: - \(2.5 \, \text{cm}^2 = 250 \, \text{mm}^2\) - \(2.05 \, \text{dm}^2 = 20500 \, \text{mm}^2\) or \(205 \, \text{cm}^2\) - \(20.5 \, \text{m}^2 = 20500000 \, \text{mm}^2\) or \(205000 \, \text{cm}^2\) Can you see how a bit of metric conversion can greatly expand your spatial understanding? Just think of it like a magical tapestry where one unit weaves into another!
