Question 203833: The perimeter of a square is 12 in. What is the area of the square?
I was unable to send a thank you to my last tutur(Stan)helper who took the time to solve my problems a couple of weeks ago because the application would not send it(it kept saying error), so just in case-Thank you so much whoever takes the time to help me out-I am drowning in geometry and I cannot tell you what a huge help this is.

Recall, the perimeter of a square formula is where "s" is the length of the side.

Start with the given equation

Plug in P=12 (the given perimeter)

Divide both sides by 4 to isolate 's'

Divide and rearrange the equation.

So the length of the side of the square is 3 inches.

Now simply plug this value into the area formula to get .

So the area of the square is 9 square inches.
