A company makes different size square containers. How can you find the length of each side if you know the perimeter of each of the containers?  Represent your answer in a table, and right and equation that shows the rule used.   You would write the equation x/4=y.  I would create an input/output table with the labels x and y.  I would then write various lengths for the perimeters and use the rule of dividing by 4 to find the y values.
