To solve the problem of finding the shaded area, we need to assume a common scenario (since the image details are not fully visible): a square with an inscribed circle, where the shaded area is the square minus the circle.

Step 1: Assume the square's side length

Let’s assume the square has a side length of 10 units (a common value in such problems).

  • Area of the square: ( \text{side}^2 = 10^2 = 100 ) square units.

Step 2: Calculate the circle's area

The circle inscribed in the square has a diameter equal to the square’s side length (10 units), so its radius ( r = 5 ) units.

  • Area of the circle: ( \pi r^2 = \pi (5)^2 = 25\pi \approx 78.5 ) square units.

Step 3: Shaded area

Shaded area = Area of square - Area of circle:
( 100 - 25\pi \approx 100 - 78.5 = 21.5 ) square units.

Answer: Approximately (\boxed{22}) (rounded to the nearest integer) or the exact value (\boxed{100 - 25\pi}).

If the shaded area is the circle, the answer is (\boxed{79}) (rounded) or (\boxed{25\pi}).

For a precise answer, please provide more details about the figure.

(\boxed{22}) (assuming the shaded area is square minus circle)
