The area of the rectangle is
5x^(2) -18x-8

Step-by-step explanation:

One side of the rectangle is
x-4

The another side of the rectangle is
5x+2

The formula to find the area of the rectangle is length × width

Area = length × width

Substituting the values, we have,

$\begin{aligned}\text { Area } &=(x-4)(5 x+2) \\&=5 x^(2)+2 x-20 x-8 \\&=5 x^(2)-18 x-8\end{aligned}$

Thus, the area of the rectangle is
5x^(2) -18x-8
