To convert area from square meters (m²) to square kilometers (km²), you can use the conversion factor that 1 km² equals 1,000,000 m² (or \(10^6\) m²).
First, let's convert 9 m² to km²:
\[ 9 \text{ m}² = \frac{9}{1,000,000} \text{ km}² = 0.000009 \text{ km}² \]
Next, for 6 km², we will convert it to m²:
\[ 6 \text{ km}² = 6 \times 1,000,000 \text{ m}² = 6,000,000 \text{ m}² \]
So,
- 9 m² is equal to 0.000009 km², and
- 6 km² is equal to 6,000,000 m².
