A square is constructed on side AD of quadrilateral ABCD such that FA lies on AB, as shown in the figure. If AD : AB = 2 : 5, the coordinates of point F are (4.4, -4.6) (4.4, -3.6) (4.6, -4.6) (4.6, -3.6) . Point E has the coordinates (2.8, -3), and the coordinates of point D are (4.4, -2.4) (4.4, -1.4) (4.6, -2.4) (4.6, -1.4) .
