Question

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)

Answer 1

i got lost

Explanation:

Answer 2

Denote the length of the overlap of the 2 segments AB=x.
Then LA=6-x and BN=10-x
6-x+x+10-x=12
16-x=12
x=4
AB=4 m
