It seems like you're referring to an area measurement or conversion, but it's a bit unclear. Let me break it down:

• "13m²" and "60m²" represent areas in square meters (m²).
• "dm²" refers to square decimeters (dm²), where 1 m² = 100 dm² because 1 meter = 10 decimeters.

Do you want to convert 13m² and 60m² to dm²? If so, here's how you'd do it:

• $13 \, \text{m}^2 = 13 \times 100 = 1300 \, \text{dm}^2$
• $60 \, \text{m}^2 = 60 \times 100 = 6000 \, \text{dm}^2$

So, 13 m² is 1300 dm², and 60 m² is 6000 dm².

Would you like more information on this conversion or any further questions about it?

Further Exploration:

1. How do you convert other units of area, like from km² to m²?
2. What is the relationship between square meters (m²) and square kilometers (km²)?
3. Can I use this conversion for other units like square centimeters (cm²)?
4. What’s the formula to calculate the area of a square or rectangle in different units?
5. How do you convert areas from imperial units (square feet, square inches) to metric units?

Tip: Remember that when converting areas, always square the linear conversion factor (like 10 for meters to decimeters) because you're working with two dimensions.
