Old macdonald was going to build a rectangular pen for some of his animals. He planned to separate them this pen into 3 pens of equal size to separate the animals. He had 200 feet of fencing to use. He wants to use all of the fencing and make the largest pen possible.
a) draw a diagram
b) identify variables
c) equation to model this information for the amount of fencing he can use. Then solve that equation for one variable.
d) write the area formula
e) substitute the equation from c into the area formula
f) use the table feature on the calculator to find the maximum area of the entire pen.
Maximum area:?
Dimensions of large pen: length=? width=?
