    Answer:

    Short piece = 13 inches

    Long piece = 52 inches.

    Step-by-step explanation:

    Let the first piece be x inches

    The second piece  = 4x

    Together they equal 5x

    x + 4x = 5x

    5x = 65 inches.    Divide both sides by 5

    5x/5 = 65/5

    x = 13 inches

    So the shorter piece is 13 inches

    The second piece is 13 * 4 = 52
