Look at the diagram.

In triangles ΔBMC and ΔDME, angle BMC = angle DME; angle BCM = angle MDE ; and DM = MC.  So the two triangles are congruent.

So, BC = DE = AD.          =>  AE = 2 AD = 2 BC

In triangles ΔALE and ΔBLC, angle ALE = angle BLC; angle LAE = LCB ; So the traingles are similar.

AB / BC = 2    =>  EL / BL = 2    => EL = 2 BL
