    Answer:

    Answer:10.875

    Step-by-step explanation:

    Let the short side be x.

    Then the long side is 3x.

    There are two opposite sides of each length, so the perimeter is

    3x + 3x + x + x = 8x

    The perimeter is 29, so we get the equation

    8x = 29

    Solve for x by dividing both sides by 8.

    x = 29/8

    x = 3.625

    The longer side is 3x.

    3x = 3(3.625) = 10.875

    Answer: 10.875
