[ASK] Geometry and Series

My partner asked me about questions no. 8 and 9.

Number 8 asks about what is the area of the quadrilateral.
Number 9 asks about what number is below the number 25.

Those are questions for Elementary School Math Olympiads in my country but both of us were having a hard time figuring them out.
For question no. 9, if only that number 9 is located right above number 13 it would be easy to solve. However, we don't know whether the placement of 9 above is intentional or not. Can someone help us solve either question?
