9. (10 points) In the $5 \times 5$ grid below, there are 6 letters. Please divide the grid along the grid lines into 6 rectangles (including squares) of different areas, such that each rectangle contains exactly one letter, and each letter is in a corner square of its rectangle. If these six letters are equal to the area of their respective rectangles, then the five-digit number $\overline{\mathrm{ABCDE}}=$ $\qquad$ .


9. (10 points) In the $5 \times 5$ grid shown, there are 6 letters. Please divide the grid into 6 rectangles (including squares) of different areas along the grid lines, such that each rectangle contains exactly one letter, and each letter is in a corner square of its rectangle. If these six letters are equal to the areas of their respective rectangles, then the five-digit number $\overline{\mathrm{ABCDE}}=34216$. [Solution] According to the analysis, since the total area $=5 \times 5=25$, the grid can be divided as shown in the figure:
$$
1+2+3+4+5=21 \text {, }
$$

We need to add 4, and the maximum can be 9, but there cannot be 7. If there is 9, then $F=9$, and the remaining 16 can only be $1+2+3+4+6$,

After trying, the result is 34216. If there is 8, then $F=8$, which is not in a corner, which does not meet the requirements.
In summary, $A=3, B=4, C=2, D=1, E=6$,
Therefore, the answer is: 34216
