Question 704198: I'm getting stuck at the end of this one...any help would be greatly appreciated!a pen with one side against a wall WITH 6M of fencing. X is the width and the length is (6-2x). The area is a=x(6-2x).
A). What dimensions of the pen will produce the maximum area?
B) what is the maximum area?
I have done the following
A=(6x-2x)
Max area occurs at axis of symmetry
X=-6/-4
3/2 is the max area
L=6-2(3/2)
Length=5.5?
I have a hard time working with fractions...any help would be greatly appreciated!

This is a parabola with a maximum
The x-coordinate of the vertex is at
width = 3/2
length =
-----------------
So, the 2 sides are 3/2 + 3/2 = 3
and the length = 3
Total length =
OK
