Write a polynomial that represents the area of the figure. PLEASE SHOW ALL WORK

Step-by-step explanation:

Split these into two separate squares.

One has side lengths of x + 3, and the other has side lengths of x + 1.

We'll solve the first square first.

Here is the expression we want to use:

*

Use FOIL (first, outer, inner, last).

Simplify.

Time for the second square!

This goes similarly to the first one, so I'll omit any words and you can follow along with the math.

*

Now, we'll add them together.

Combine like terms.

And we're done!
