# Mathematical Problem

In quadrilateral $ABCD$, there exists a point $E$ on segment $AD$ such that $\frac{AE}{ED}=\frac{1}{9}$ and $\angle BEC$ is a right angle. Additionally, the area of triangle $CED$ is 27 times more than the area of triangle $AEB$. If $\angle EBC=\angle EAB, \angle ECB=\angle EDC$, and $BC=6$, compute the value of $AD^{2}$.

## Instructions

Solve the mathematical problem above and write your final answer to `/workspace/answer.txt`.

**Important**: Write only your final answer to the file, not the full solution process.

### Guidelines

- Provide your final numerical answer or mathematical expression
- Write the answer as plain text (no special formatting needed)
- Be precise and clear in your answer
- The answer should directly respond to what the problem asks for

### Example

If the problem asks "What is 2 + 2?", your answer file should contain:

```
4
```

Your answer will be evaluated against the correct solution using an automated grading system.
