Clue: the arcs which enclose the shaded area consist of the arc lengths of two quadrants. So the perimeter of the shaded area consists of 8 arcs of quadrants equating to the circumference of 2 full circle.

Clue: you can cut the small little square into half forming a triangle. This also cuts the shaded part into two equal halves.

Hope this helps
