Peter has 1200 yards of fencing to enclose a rectangular area. Find the dimensions of the rectangle that maximize the enclosed area?

It's a square.

So what exactly would the answer be? im confused..

1200/4 = 300 yards on each side.
A = 300 * 300
A = ? 
Oh i see now! Ok thank you!

Finding the Absolute Area....
Area of the fence:
A=x*y
Perimeter of the fence
2x+2y=1200
Then, you solve for one variable
2x=12002y
x=600y < plug this back into the Area function and you will get
A=(600y)y
A=600yy^2
And I believe you can set that equal to zero
y^2+600y=0
Then you use the quadratic formula
b=600
a=1
so y= 600/(2)*(1)
y=300
That'll give you one side, then plug it back to perimeter equation to get x. Hope this is right! 
You're welcome.
