    Given that the total area of the walkway and the pool is w²+17w+66, and the width w, will be found as follows:

    A=length*width

    A=w²+17w+66

    to get the new width we need to factorize the above quadratic form

    A=w²+17w+66

    =w²+11w+6w+66

    =w (w+11) + 6 (w+11)

    = (w+11) (w+6)

    From the answer, the width=6 units, length=11 units
