    Optimization

    A contractor wishes to brace a newly built wall by supporting it with a wooden beam. Unfortunately, the new wall is only 4 feet from a 5 ft. high fence and so the beam must go over the fence as shown in the sketch below. Determine the length of the shortest beam that can be used.

    |<----------------------Wall
    |
    |\
    |..\
    |....\<--------------------Beam
    |......\
    |......|\
    |......|..\
    |......|<----------------5 ft
    |......|......\
    ----------------------------------------------
    ...^...
    ...|....
    ...|....
    ...4 ft


    Thanks
