Step-by-step explanation:
The perimeter of the region is equal to the sum of the perimeter of the four semicircular arc. Since the semicircular arcs have the same measure, therefore:

The side of the square = diameter of the semicircle = 2/π.
The radius of semicircle = diameter/2 = 
The perimeter of a semicircle = perimeter of a circle ÷ 2
