    Answer:

    length = 12

    width = 15

    Step-by-step explanation:

    if you foil (x+7)(x+10) you get:

    x²+17x-110 = 0

    the factors are:

    (x+22)(x-5) = 0

    x = -22 and 5

    we can dismiss the negative as irrelevant for a measure; therefore, x = 5

    length = 5+7, or 12

    width = 5+10, or 15
