SOLUTION
Step 1:
The area of the shaded figure =
Area of the square - area of the circle
Step 2: Find the area of the square
To find the length of the square, we have to use the diameter of the circle.
The diameter of the circle d:
The diameter of the circle is also the length of the outer square.
Therefore length of square (l) = diameter of circle = 24cm
Area of square
Step 3: Find the area of the circle
Step 4: Find the area of the shaded figure.
The area of the shaded figure =
Area of the square - area of the circle
The area of the shaded figure =
Conclusion: The area of the shaded figure is
