The area of the pen is the products of its dimensions
- The dimension of the pen is 300 by 120 feet
- The maximum area of the pen is 36000 square feet.
Let the dimension of the fence be x by y.
So, we have:
<em />
<em> --- perimeter</em>
<em />
<em> -- area</em>
<em />
Subtract 5y from both sides of 

Divide both sides by 2

Substitute
in 


Split

Differentiate

Set to 0

Add 5y to both sides

Divide both sides by 5

Substitute
in 




Recall that:

So, we have:


Hence, the maximum area of the pen is 36000 square feet.
