    For this case we observe that the dimensions of the original piece are:

    3 feet

    2.5 feet

    Let's multiply these dimensions by a scale factor k:

    3 * k

    2.5 * k

    We match the new dimensions with their respective values:

    3 * k = 6

    2.5 * k = 5

    Clearing k we have:

    k = 6/3 = 2

    k = 5 / 2.5 = 2

    Since the value of k is the same, then the pieces are similar.

    Answer:

    The pieces are similar.

    The ratio of their corresponding side lengths is:

    k = 2
