Answer:
(x²+3x)
Explanation:
First, divide the figure into two rectangles as done below:
Next, calculate the area of each of the rectangles and add:
[tex]\text{Area}=(6\times x)+x(x-3)[/tex]
Finally, express the area as a polynomial in standard form:
[tex]\begin{gathered} \text{Area}=6x+x^2-3x=x^2+3x \\ \text{Area}=(x^2+3x)\text{ square units} \end{gathered}[/tex]
