Answer:

C. x²+12x+36

Step-by-step explanation:

Since a square's area is figures out with length^{2} and since the length is x+6, then we get:

(x+6)²=

(x+6)(x+6)=

<em>Use </em><em>FOIL</em><em> method.</em>

First: x²

Outer: 36

Inner: 6x

Last: 6x

x²+36+6x+6x=

x²+12x+36

The answer that fits is C. x²+12x+36.
