    Answer:

    Step-by-step explanation:

    Let the width be w centimeters.

    Then the length = w + 7.

    The area A is found from the length multiplied by the width.

    330 = w(w + 7) = w^2 + 7w.

    Now we can rearrange this equation to form a quadratic, as follows:

    The factorization of the quadratic is:

    (w + 22)(w – 15) = 0

    Therefore we find that:

    width = 15 centimeters

    length = 22 centimeters
