Let ABC is a triangle having right angle at A with vertices A, B, C in the anti-clockwise sense in that order. $A(1,2) B(-3,1)$  and vertex C lies on the X – axis. And BCDE forms a square with the vertices B, C, D, E in the clockwise sense in the same order. Then the value of ‘4(Area of the square BCDE)’ is ------
