Question 439871
The third side has to be greater than 3 and less than 13.


The other tutor let c = 12, since 12 is the integer less than 13. However, c can be 12.9, or 12.99999... as long as it is less than 13. The largest possible value of the perimeter is roughly 5 + 8 + 13, or 26 (infinitesimally smaller than 26).
