3) Two vertical poles are erected 3 meters apart. One pole has height 1 meter, and the other pole has height3 meters. A short metal hook is screwed into the ground at some point between the two poles. The topsof the two poles are connected by a string that passes through the hook between the poles. What is theshortest possible length of the string? Simplify your answer as much as possible.

Let AB and ED be the poles and BD denotes the distance between them. ACE be the string.(The figure…
