#2**+3 **

Hey GAMEMASTERX40!

The formula to find the area of a square is L^2, where L is the side length.

Therefore, to find the side length of square #1, we want to find the square root of x^2+4x+4.

We can factor this, since it’s a perfect square:

x^2+4x+4=(x+2)^2, the side of the square is x+2.

Therefore, the side length of square #3 is twice of this, or 2x+4.

The area of square #3 must be (2x+4)^2.

I hope this helped,

Gavin
