Answer:
Given Radius= 12 cm
To find the area of
the shaded part.
Solution

Let the length of the side of the square be x.
The length of side of Square.
Diagonal of Square = Diameter
of square.
a² + 6²
=
x² + x² = 24² 2x² = 576
x² = 288 FJ288
x
Area of square= length x Length
= 288 cm² Area of circe= π 0² - π (12)² = 144π cm²
=
Area of 4 shaded parts = 144st - 288
