We know from the triangle inequality that the last side, $s$, fulfills $s+2\textgreater5$. Therefore, $P\textgreater5+5$. The least integer value of $P$ is $11$ 
For $\triangle ABC$, all its side lengths are integer. The primeter of $\triangle ABC$ with a side of length $2$ and a side length of $5$ is at least ．

a: $$7$$ 
b: $$8$$ 
c: $$9$$ 
d: $$11$$
