It sounds like F is a midpoint of DC or DA.
This makes the sides of the square = 8radical2
and then the area of ABCD is (8radical2)^2.
A sneaky way is to imagine (or draw) 8 congruent triangles all matching DEF. Then imagine cutting them out and reassembling them to make two squares with sides of 8. So the answer is 128 u^2.
