mathematics ? I would like tosolve this problem withthe step .see below thank you

This is the method presented in the text for finding a circle whose area is equal to a given square: In square ABCD, let M be the intersection of the diagonals (see figure 8.5). Draw the circle with M as center and M A as radius: Let M E be the radius of the circle perpendicular to the side AD and cutting AD in G. Let GN= 1/3 GE. Then MN is the radius of the desired circle. Show that if AB=s and MN=r, then r/s=(2+?2)/6. Show that this implies a value for ? equal to 3.088311755
