    Answer:

    The scale factor is equal to 2

    Step-by-step explanation:

    we know that

    If two figures are similar, then the ratio of its areas is equal to the scale factor squared

    Let

    z —-> the scale factor

    x —-> the area of polygon d

    y —> the area of polygon c

    so

    z^{2}=\frac{x}{y}

    we have

    x=28\ units\^{2}

    y=7\ units\^{2}

    z^{2}=\frac{28}{7}

    z^{2}=4

    z=2

    therefore

    The scale factor is equal to 2
