Exam Point: Garden, Area of Composite Figures
Analysis: The four leaf-shaped figures in the middle can be divided into two halves, which can perfectly fill the blank spaces outside the square. Therefore, the area of the large circle minus the area of the inscribed square is the area of the shaded part.
$$
S_{\text {shaded }}=\pi \times 2^{2}-\frac{4 \times 4}{2}=4 \pi-8
