Which polynomial expression represents the area of the outermost square tile, shown below?

The bottom of the square is x + 3

x^2 + 6x + 6
x^2 + 9x + 6
x^2 + 6x + 9
x^2 − 6x + 9

I have attached a picture of the problem so it's easier to understand.

funny enough, it is the one that you clicked on. the of the square simple needs to be squared to find the answer.
I hope this helped.

By definition, we have that the area of a square is given by:

A = L ^ 2
Where,
L: square side
We have that the side of the square is given by:

L = x + 3
Substituting values:

A = (x + 3) ^ 2
Rewriting the expression we have:

A = x ^ 2 + 6x + 9
Answer:
The area of the outermost square tile, shown below is:

x ^ 2 + 6x + 9
