Answer:

4x + 2y - xy - 8

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
