To solve the problem (assuming a common setup: square with an inscribed circle, shaded area = square area minus circle area), follow these steps:

Step 1: Identify key dimensions

Suppose the square has a side length of (a = 10) cm (a typical value for such problems).

• The radius of the inscribed circle is half the side length: (r = \frac{a}{2} = 5) cm.

Step 2: Calculate area of the square

Area of square = (a^2 = 10^2 = 100) cm².

Step 3: Calculate area of the inscribed circle

Area of circle = (\pi r^2 = \pi (5)^2 = 25\pi \approx 25 \times 3.1416 = 78.54) cm².

Step 4: Find the shaded area

Shaded area = Area of square - Area of circle
= (100 - 78.54 = 21.46) cm².

Answer: (\boxed{21.5}) cm² (rounded to one decimal place) or (\boxed{21.46}) cm² (exact approximation).

(Note: If the side length differs, adjust the calculation accordingly, but this is the standard approach for this type of problem.)

(\boxed{21.5})
