10、As shown in the figure, in square $\mathrm{ABCD}$, $\mathrm{E}$ and $\mathrm{F}$ are the points that bisect and trisect the sides $\mathrm{AB}$ and $\mathrm{BC}$, respectively. It is known that the area of triangle $\mathrm{ADE}$ is 27 more than the area of triangle $\mathrm{CDF}$. The area of square $\mathrm{ABCD}$ is $\qquad$ $—^{\circ}$
【Analysis】Assuming the area of the square is 12 parts, then the area of triangle $\mathrm{ADE}$ is 3 parts, and the area of triangle $\mathrm{CDF}$ is 2 parts, differing by 1 part. Therefore, 1 part is 27, so the area of square $\mathrm{ABCD}$ is $12 \times 27=324$
