    Answer:

    The parts are 27 cm and 64 cm long.

    Step-by-step explanation:

    Let the shorter part be x.

    “The longer part is 10 cm more than twice as long as the shorter part.”

    shorter part: x

    longer part: 2x + 10

    total length: x + 2x + 10

    total length: 91

    x + 2x + 10 = 91

    3x + 10 = 91

    3x = 81

    x = 27

    2x + 10 = 2(27) + 10 = 54 + 10 = 64

    Answer: The parts are 27 cm and 64 cm long.
