35. Super Wings LeDy is folding a part of a paper airplane. As shown in Figure 1, he first divides a rectangular piece of paper with an area of $60 \mathrm{~cm}^{2}$ into two equal parts using line segment $M N$, then folds the rectangular paper along $M N$ to get Figure 2, and then folds Figure 2 along the axis of symmetry to get Figure 3. In Figure 3, the area of the red quadrilateral is twice the sum of the areas of the two blue triangles. Therefore, the area of the red quadrilateral is $\qquad$ $\mathrm{cm}^{2}$.
