    4x + 2y - xy - 8

    Step-by-step explanation:

    The area (A) of a rectangle is calculated as

    A = length * width, that is

    A = (x - 2) (4 - y)

    Each of the terms in the second factor is multiplied by each of the terms in the first factor, that is

    x (4 - y) - 2 (4 - y) ← distribute both parenthesis

    = 4x - xy - 8 + 2y, thus

    A = 4x + 2y - xy - 8
