    The sides of this triangle are 5x, 6x abd 7x,

    The perimeter of a triangle is the sum of all sides

    We can suggest this inequation:

    5x+6x+7x<54

    18x<54

    x<54/18

    x<3

    Therefore the lenght of the longest side would be:

    7x< (7*3)

    7x<21

    Answer: the lenght of the longest side would be <21
