To solve the problem (assuming the common scenario of a square with side length 10 cm and an inscribed circle, where the shaded area is the square minus the circle):

Step 1: Calculate the area of the square

The side length of the square is 10 cm.
Area of square = side × side = (10×10 = 100) cm².

Step 2: Calculate the area of the inscribed circle

The diameter of the circle equals the side length of the square (10 cm), so the radius (r = 5) cm.
Area of circle = (\pi r^2 = 3.14×5^2 = 3.14×25 = 78.5) cm².

Step 3: Find the shaded area

Shaded area = Area of square - Area of circle = (100 - 78.5 = 21.5) cm².

Answer: (\boxed{21.5}) cm². (Or (\boxed{100 - 25\pi}) if exact form is needed.)

But typically, the numerical value is expected, so (\boxed{21.5}).

(Note: If the shaded area is the circle, the answer would be (\boxed{78.5}), but based on common problems, the shaded area is usually the square minus the circle.)

Final answer: (\boxed{21.5}) (or (\boxed{78.5}) if the circle is shaded, but likely (\boxed{21.5})).

Assuming the most common case:
(\boxed{21.5}) cm².

If we need to write it as an integer (rounded), it could be (\boxed{22}), but 21.5 is precise.

But let's confirm: 100 - 25×3.14 =100-78.5=21.5, so the answer is (\boxed{21.5}).

(\boxed{21.5}) is the correct answer here.

Final Answer
(\boxed{21.5})
