To convert from cm² to m², you can use the fact that 1 m² = 10,000 cm². Therefore, to convert an area in cm² to m², you divide the area in cm² by 10,000.
Here are the conversions for the areas you provided:
- 40000 cm² = \( \frac{40000}{10000} = 4 \) m²
- 600000 cm² = \( \frac{600000}{10000} = 60 \) m²
- 900 cm² = \( \frac{900}{10000} = 0.09 \) m²
- 70000 cm² = \( \frac{70000}{10000} = 7 \) m²
- 3830000 cm² = \( \frac{3830000}{10000} = 383 \) m²
- 4421 cm² = \( \frac{4421}{10000} = 0.4421 \) m²
- 180000 cm² = \( \frac{180000}{10000} = 18 \) m²
- 2500 cm² = \( \frac{2500}{10000} = 0.25 \) m²
- 12 cm² = \( \frac{12}{10000} = 0.0012 \) m²
Here are the final results in m²:
- 40000 cm² = 4 m²
- 600000 cm² = 60 m²
- 900 cm² = 0.09 m²
- 70000 cm² = 7 m²
- 3830000 cm² = 383 m²
- 4421 cm² = 0.4421 m²
- 180000 cm² = 18 m²
- 2500 cm² = 0.25 m²
- 12 cm² = 0.0012 m²
