The repeated shaded area between the circle and the square is a 1/4 circle.
Hence the shaded area = Area of the square – Area of the 1/4 circle – Area of the 1/4 circle + Area of the circle
Shaded area = Area of the square + Area of the 1/2 circle
= 10² + 1/2 × 5²π
Assume π = 3.14
Shaded area = 100 + 39.25 = 139.25 cm²
If you flap the corner 1/4 circle in white horizontally 180 degree
Perimeter = Perimeter of the circle + 5 x 4 = 2 x 5π + 20 = 31.4 + 20 = 51.4 cm
