Suppose that half a piece of wire is bent to construct a perfect square. Express the area of the square as a function of the length of the original piece of wire.

Let the side of the square measure X.
The area is X^2.
The perimiter of the square is 4X
and the length of the original piece of wire is 8X.

Um... sas857, can you post the answer that you think is good now? It'll tell us whether you understood or not.
