GRE In the figure above, if sides LM .jpg
In the figure above, if sides LM and NM are cut apart from each other at point M, creating 2 free-swinging segments, and each is folded down to LN in the directions shown by the arrows, what will be the length, in meters, of the overlap of the 2 segments? (Disregard the thickness of the segments.)
Kudos for the right answer and explanation
So, if sides LM and NM are lying on side LN (which has length 12), the overlap will equal 16 - 12 = 4
