Two squares with side  $12$  lie exactly on top of each other.
One square is rotated around a corner point through an angle of  $30$  degrees relative to the other square.
Determine the area of the common piece of the two squares.

unitsize (2 cm);

pair A, B, C, D, Bp, Cp, Dp, P;

A = (0,0);
B = (-1,0);
C = (-1,1);
D = (0,1);
Bp = rotate(-30)*(B);
Cp = rotate(-30)*(C);
Dp = rotate(-30)*(D);
P = extension(C, D, Bp, Cp);

fill(A--Bp--P--D--cycle, gray(0.8));
