We can solve this by calculating the area of the square and subtracting the area of the inscribed circle. The area of the square is:


Square=10\cdot10=100cm^2

The formula for the area of a circle is:


A=\pi r^2

The radius of the inscribed circle is half the length of the side of the square, then, the radius is r = 5 cm


Circle=\pi5^2=25\pi\text{ }cm^2

Now, we rest:


Square-Circle=100cm^2-25\pi cm^2\approx21.46cm^2

The answer is 21.46cm²
