The drivers of deforestation vary significantly between different tropical rainforest regions. The table below shows the proportion of deforestation attributed to different drivers in three major rainforest regions.
| Tropical Rainforest Region | Commercial Agriculture | Subsistence / Shifting Agriculture | Logging | Infrastructure and Mining |
|---|---|---|---|---|
| Amazon (South America) | 70% | 15% | 10% | 5% |
| Congo Basin (Africa) | 10% | 65% | 15% | 10% |
| Southeast Asia | 50% | 25% | 15% | 10% |
In a given year, an environmental monitoring agency records a total forest loss of 12,000 km212,000\text{ km}^212,000 km2 across these three regions, distributed as follows:
Using the data provided, calculate the total area (in km2\text{km}^2km2) deforested due to commercial agriculture across all three regions combined.
