14. As shown in the figure, four rectangles, Jia, Yi, Bing, and Ding, are pieced together to form square $E F G H$, with the middle shaded area being a square. It is known that the sum of the areas of rectangles Jia, Yi, Bing, and Ding is $32 \mathrm{~cm}^{2}$, and the area of quadrilateral $A B C D$ is $20 \mathrm{~cm}^{2}$. Find the total perimeter of rectangles Jia, Yi, Bing, and Ding in centimeters.
【Solution】Solution: $S_{\text {ming }}=20-\frac{1}{2} \times 32=4$ (square centimeters),
Area of the square $=32+4=36$ (square centimeters),
Side length of the square $=6$ (centimeters);
The total perimeter of rectangles Jia, Yi, Bing, and Ding: $4 \times 6 \times 2=48$ (centimeters).
Answer: The total perimeter of rectangles Jia, Yi, Bing, and Ding is 48 centimeters.
