Measure of Nonagon (9-sided polygon) = 1260°
Each angle measure = 1260 ÷ 9 = 140°
The value of x (the outside angle) = 180° - 140° = 40°

Answer:
5600 square feet is the area.
Step-by-step explanation:
Perimeter will be = 300 feet
Length of the fence enclosure must be at least 80 feet.
Width of the fence enclosure must be at least 40 feet.
Let x be the length and y be the width of the court.
We get following constraints:


If we calculate the area, we get 
And for the perimeter we get:
⇒ 
Now look at the graph attached, we get point (80,70) as the possible solution.
So, the maximum area occurs when the dimensions are 80 feet by 70 feet.
