The image contains several unit conversions for area, involving square centimeters (cm²), square decimeters (dm²), square meters (m²), and possibly hectares (ha).

To provide you with more precise help, I'll walk through a couple of these conversions based on typical area relationships between units.

Some common area conversions are:

1. $1 \, \text{m}^2 = 100 \, \text{dm}^2 = 10,000 \, \text{cm}^2$
2. $1 \, \text{ha} = 10,000 \, \text{m}^2$

If you'd like, I can analyze the image more closely to extract specific numbers. Could you confirm if you're working on conversions, or if you'd prefer a detailed interpretation of specific calculations from the image?
