As illustrated, in a
trapezoid ABCD (AD // BC), AC and BD meet at E. F is the midpoint of BC.
EF and AB extended meet at G. AF and BH meet at J. CH and DF
meet at L. GJ extended meets AD at K, GE extended meets AD at H, and GL extended meets AD at
M. If the area of triangle AGK is 10, find the area of triangle
KGM.
