In the figure, there is a circle of radius 11 such that the segment AGAG is diameter and that line AFAF is perpendicular to line DCDC. There are also two squares ABDCABDC and DEGFDEGF, where BB and EE are points on the circle, and the points AA, DD and EE are collinear. What is the area of square DEGFDEGF? https://cdn.artofproblemsolving.com/attachments/1/e/794da3bc38096ef5d5daaa01d9c0f8c41a6f84.png
