He needs two adjacent rectangular enclosures  he has 300 feet of fencing.
a. find a function that models the total area of enclosures with respect to the width of the enclosures.
b. write your function in vertex form using the vertex formula.
c. what is the largest area that farmer jack can enclose?
d. how should he use the fencing?
*use graphing calculator for a & b to verify*

To make the question "interesting", usually there is a common side for the two adjacent rectangles
Otherwise they would simply have to be 2 equal squares.
Did you have a diagram to show it ?
