Isoperimetric Theorem what does it mean

[ultrabionic_ang]

so i was reading something on the isoperimetric theorem at this link:http://www.cut-the-knot.org/do_you_know/isoperimetric.shtml"

and I'm having a difficult time trying to understand it, much less put the theorem into my own words.

If you were designing a fence to enclose a certain set area, what shape would you create with the fence so that you use the least amount of fencing material ? The theorem states that the circle is that shape.

Seems pretty straightforward to me.
