Answer :

Sure! Let's convert an area of 3.9 square meters (m²) into square centimeters (cm²) step by step.

1. Understand the Conversion Factor:
- We need to convert from square meters to square centimeters.
- We know that 1 meter (m) is equal to 100 centimeters (cm).
- Therefore, 1 square meter (m²) is equal to [tex]\(100 \times 100\)[/tex] square centimeters (cm²).

2. Calculate the Conversion Factor:
- [tex]\(1 \text{ m}^2 = (100 \text{ cm}) \times (100 \text{ cm})\)[/tex]
- [tex]\(1 \text{ m}^2 = 10,000 \text{ cm}^2\)[/tex]

3. Convert the Given Area:
- We have 3.9 square meters to convert.
- Multiply the area in square meters by the conversion factor to get the area in square centimeters.

So, we perform the calculation:
- [tex]\(3.9 \text{ m}^2 \times 10,000 \text{ cm}^2/\text{m}^2 = 39,000 \text{ cm}^2\)[/tex]

In conclusion, an area of 3.9 square meters is equivalent to 39,000 square centimeters.
