Answer :

Sure! Let's clarify the concepts and relationships between different units of area measurement.

### Understanding Units
1. Hectares and Acres: These are both units used to measure large areas of land.
- 1 hectare (ha) is equivalent to 10,000 square meters (m²).
- 1 acre is equivalent to 4,840 square yards or approximately 4,047 square meters (m²).

2. Square Meters: This is the SI unit used for measuring small and large areas, including land.

### Converting Acres to Square Meters
To find how many square meters make up 49 acres:
- 1 acre ≈ 4,047 m²
- Therefore, to convert acres to square meters, you multiply the number of acres by the conversion factor (4,047).

### Calculation Steps:
1. Identify the given number of acres:
- Given: 49 acres

2. Conversion factor:
- 1 acre = 4,047 m²

3. Compute the area in square meters:
[tex]\[ \text{Area in square meters} = 49 \, \text{acres} \times 4,047 \, \text{m²/acre} \][/tex]

4. Multiplying:
- [tex]\( 49 \times 4,047 = 198,303 \, \text{m²} \)[/tex]

### Conclusion
Therefore, 49 acres is equivalent to 198,303 square meters.
