Consider the unit square $ABCD$ . Let points $E,F,G,$ and $H$ be the midpoints of sides $\overline{AB},\overline{BC},\overline{CD},$ and $\overline{AD},$ respectfully. Then, segments $\overline{EG}$ and $\overline{FH}$ intersect at point $X$ . Points $J,K,L,$ and $M$ are the midpoints of $\overline{XE},\overline{XF},\overline{XG},$ and $\overline{XH},$ also respectfully. Draw triangles $\triangle AJM$ , $\triangle BKJ$ , $\triangle CLK$ , and $\triangle DML$ . Points $A$ , $B$ , $C$ , and $D$ fold up to form the apex of a square pyramid with base $JKLM$ . Find the area of the square pyramid.
