To solve the problem of finding the shaded area (assuming the common scenario of a square with side length 10 cm containing four quarter-circles forming a full 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 circle

The four quarter-circles inside the square form a full circle. The radius of the circle is half the side length of the square: (r = 10/2 = 5) cm.
Area of circle = (\pi r^2 = \pi×5^2 = 25\pi ≈ 25×3.14 = 78.5) cm².

Step 3: Find the shaded area

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

Answer: 21.5 cm². (If the side length is different, adjust accordingly, but this is the most common result.)

(\boxed{21.5})
