    Greatest possible value for the width is 10.6 centimeters.

    D. 2w+2 * (46) > 106

    Step-by-step explanation:

    Perimeter of a rectangle = 2 (l + w)

    From the given question, P = 106 and l = 4w

    So that,

    106 = 2 (4w + w)

    106 = 2 (5w)

    106 = 10 w

    w = 10.6 centimeters

    So, the greatest possible value for the width is 10.6 centimeters.

    Model; 2w+2 * (46) > 106

    = 2 * 10.6 + 2 * (46)

    = 113.2

    113.2 is greater than 106
