The maximum area of the pen is the highest area the pen can have
The maximum area is 16200 square yards
Let the dimension be x and y.
So, the perimeter is given as:

Because it has one additional fence, the perimeter is calculated as:

Make y the subject

The area is calculated as:

Substitute 

Expand

Differentiate

Set to 0

Rewrite as:

Divide both sides by 4

Substitute 90 for x in 


Hence, the maximum area is 16200 square yards

Supplementary angles are two angles that when add equal 180 degrees.
The supplement of an angle is 180 - n.
n = 17(180 - n)
n = 3060 - 17n
n + 17n = 3060
18n = 3060
n = 3060/18
n = 170
so the unknown angle (n) = 170 degrees and its supplement = (180 - 170 = 10)......= 10 degrees.
