    Width = 12

    Length = 15

    Step-by-step explanation:

    Area = length * width

    180 = w * (w+3)

    180 = w^2 + 3w

    0 = w^2 + 3w - 180

    Use the quadratic to solve for w

    w = 12, w=-15

    Negative lengths don't make sense so 12 = w

    l=w+3

    l=12+3

    l=15

    Length is 15

    Width is 12

    Step-by-step explanation:

    l=3+w

    A=180

    180 = (3+w) w

    180=w^2+3w

    0=w^2+3w-180

    w=12 or - 15

    w can not be negative so it equals 12.

    l=12+3

    l=15

    I don't understand the last part of your question. inic 10 cm?
