Circles Part 2

Let a circle C1 be obtained on rolling the circle x2+y2−4x−6y+11=0 upwards 4 units on the tangent T to it at the point (3,2). Let C2 be the image of C1 in T. Let A and B be the centers of circles C1 and C2 respectively, and M and N be respectively the feet of perpendiculars drawn from A and B on the x-axis. Then the area of the trapezium AMNB is :
