You can use
Sine25=9/c
Or
Sin25/9=sine 90/c
You need to find the area of the hexagon, and the area of the triangle.
The formula for the area of a triangle is

I hope this helps you a little.
If you let x = 13:
Then, Area = 2(13)^2 - 5(13)
= 338 - 65
= 273 sq ft
If you let 2x-5 = 13:
2x = 18
x = 6
Then, Area = 2(6)^2 - 5(6)
= 72 - 30
= 42 sq ft
Therefore, your options are A or C. Your answer can be chosen based on what you assume the width to be. Good luck!
