We know from the triangle inequality that the last side, $s$, fulfills $s\textless12+13$. Adding $12+13$ to both sides of the inequality, we get $s+12+13\textless50$, and because $s+12+13$ is the perimeter of our triangle, (B) 50 is our answer. 
What is the smallest whole number larger than the perimeter of any triangle with a side of length $12$ and a side of length $13$? (adapted from 2015 AMC8, Question 8) 
Options:
A. $$25$$ 
B. $$50$$ 
C. $$51$$ 
D. $$49$$ 
E. $$33$$
