Let  $ABCD$  be a rectangle with  $AB = 6$  and  $BC = 6 \sqrt 3$ .  We construct four semicircles  $\omega_1$ ,  $\omega_2$ ,  $\omega_3$ ,  $\omega_4$  whose diameters are the segments  $AB$ ,  $BC$ ,  $CD$ ,  $DA$ . It is given that  $\omega_i$  and  $\omega_{i+1}$  intersect at some point  $X_i$  in the interior of  $ABCD$  for every  $i=1,2,3,4$  (indices taken modulo  $4$ ). Compute the square of the area of  $X_1X_2X_3X_4$ .
