    14 feet

    Step-by-step explanation:

    To calculate the width of the patio, we will use the formula of the perimeter, in the case of the rectangle it has the formula of:

    p = 2 * l + 2 * w

    Now we know that the total fencing value is $ 976 and that per foot is $ 16

    that is, we can calculate the value of the perimeter, like this:

    976/16 = 61

    We know that the perimeter is 61 feet and that the length is 16.5, therefore it only remains to replace:

    61 = 16.5 * 2 + 2 * w

    solving for w:

    w = (61 - 33) / 2

    w = 14

    which means that the width of the patio is 14 feet.
