    Short side length = x

    Medium side = x + 7

    Long side = 5x

    Total 49, so

    x + x + 7 + 5x = 49

    If you combine like terms:

    7x + 7 = 49

    Subtract 7 from both sides

    7x = 42

    Divide both sides by 7

    x = 6 inches

    shortest side=6 inches

    Step-by-step explanation:

    Let the shortest side=x

    then x + (x+7) + 5x=49

    7x=49-7=42

    x=42/7=6

    shortest side=6 inches
