    The first is x

    the 2nd is 3 times the first or 3x

    the third is 2 times long as the 2nd piece or 2 (3x) or 6x

    total length=1st piece+2nd piece+3rd piece

    48.5=x+3x+6x

    48.5=10x

    divide by 10

    4.85=x

    3x=14.55

    6x=29.1

    the 3 pieces are 4.85cm, 14.55cm and 29.1cm
