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:
 [tex]A = L ^ 2 [/tex]
 Where,
 L: square side
 We have that the side of the square is given by:
 [tex]L = x + 3 [/tex]
 Substituting values:
 [tex]A = (x + 3) ^ 2 [/tex]
 Rewriting the expression we have:
 [tex]A = x ^ 2 + 6x + 9 [/tex]
 Answer:
 The area of the outermost square tile, shown below is:
 [tex]x ^ 2 + 6x + 9[/tex]
