    By definition, the area is given by:

    A = w * l

    Where,

    w: width

    l: length

    We have two expressions for the length:

    L = 14//L = 5 + 3c

    Since the length is the same, we equate both expressions:

    5 + 3c = 14

    From here, we clear the value of c:

    3c = 14 - 5//3c = 9

    c = / frac{9}{3}//c = 3

    Then, we have that the width is given by:

    W = 6c-8

    Substituting the value of c we have:

    W = 6 (3) - 8//W = 18-8//W = 10

    Finally, the area is given by:

    A = w * l//A = 10 * 14//A = 140 ft ^ 2

    Answer:

    he should order 140 square feet
