    Answer:

    Step-by-step explanation:

    The area of a pentagon = a * p / 2

    Area = 336 mm^2

    a = 9.6 mm

    336 = 1/2 * 9.6 * p        Multiply by 2

    672 = 9.6 p                  Divide by 9.6

    672/9.6 = 9.6 * p / 9.6

    70 = p

    A pentagon has 5 sides

    s = p / # sides

    s = 70 / 5

    s = 14
