Asquare has a side length of 12 mm. find the area of the square.

For this case we have that by definition, the area of a square is given by:

Where "l" represents the side of the square.

In this case we have to:

So, the area is given by:

Thus, the area of a square whose side is 12mm, is given by:

29 is the correct answer

step-by-step explanation:

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
