Answer:
360 in²
Step-by-step explanation:
The given figure is a wedge.
If you need the surface area then,
Height×Base=(9×12)=108 in²
2nd Base×Length=(3×15)=45 in²
Height×2nd base=(9×3)=27 in²
Base×Length=(12×15)=180 in²
Then add all of them=(108+45+27+180)in²
=360 in²
∴The area of the wedge is 360 in²
