The task is to find the shaded area in the given image.

The figure appears to show a circle that is divided into four equal parts. Two of these parts are shaded, and two are not. The shading pattern suggests symmetry and equal division.

### Steps to calculate the shaded area:

1. **Area of the Circle**: 
   The first step is to calculate the area of the entire circle. The formula for the area of a circle is:
   
   \[
   A_{\text{circle}} = \pi r^2
   \]
   where \( r \) is the radius of the circle.

2. **Fraction of the Shaded Area**:
   The circle is divided into four equal parts, and two of these parts are shaded. Therefore, the shaded area is half of the total area of the circle:
   
   \[
   A_{\text{shaded}} = \frac{2}{4} \times A_{\text{circle}} = \frac{1}{2} \times A_{\text{circle}}
   \]

3. **Final Expression**:
   Thus, the shaded area is:
   
   \[
   A_{\text{shaded}} = \frac{1}{2} \times \pi r^2
   \]

To proceed further, we would need either the radius \( r \) of the circle or any additional details provided in the full problem.
