Answer:

D

Step-by-step explanation:

The dimensions of the portrait are attached.

The total area of the portrait is represented by its width 5+x and its length x+1.

We know by definition that the area of a rectangle is

[tex]A= w \times l[/tex]

Where [tex]w[/tex] is the width and [tex]l[/tex] is the length.

Using the given expressiones, we have

[tex]A=(5+x)(x+1)=5x+5+x^{2} +x=x^{2} +6x+5[/tex]

Therefore, the right answer is D.
