h = 26 is the given height of the equilateral triangle
s = unknown side length of the equilateral triangle
The formula to use is
s = (2/3)*sqrt(3)*h
which helps tie together the side length s and the height h
Plug in the given height h = 26 and we get...
s = (2/3)*sqrt(3)*h
s = (2/3)*sqrt(3)*26
s = 30.0222
That rounds to 30
Answer: 30
