The first thing you should do is use the fact that the area of the triangle is:
A = b * h * (1/2).
From there you clear the height as a function of "c"
Then you will have a polynomial division which you must make to find the height of the triangle.
I attach the solution.
Answer:
Option B 1/64
Step-by-step explanation:

Hope this helps
C never, there are always different methods to solve a problem but don't forget that the equation always stays the same!
