1. **Compound Leaf**: A leaf where the blade is divided into multiple distinct leaflets.
2. **Total Area Calculation**: The total surface area available for photosynthesis is the sum of the areas of all leaflets.
3. **Identify Given Values**:
   - Number of Leaflets = $12$.
   - Average Area per Leaflet = $15 \ cm^2$.
4. **Calculation**:
   - $Total \ Area = 12 	imes 15$
   - $12 	imes 10 = 120$
   - $12 	imes 5 = 60$
   - $Total \ Area = 120 + 60 = \mathbf{180 \ cm^2}$.
5. **Conclusion**: The total photosynthetic area is $180 \ cm^2$.
