+68 In rectangle \(ABCD\), points \(F\) and \(G\) lie on \(\overline{AB}\) so that \(AF = FG = GB\) and \(E\) is the midpoint of \(\overline{DC}\). Also, \(\overline{AC}\) intersects \(\overline{EF}\) at \(H\) and \(\overline{EG}\) at \(J\). The area of rectangle \(ABCD\) is 70. Find the area of triangle \(EHJ\).
