The adjacent sides of the decagon shown meet at right angles.  What is its perimeter?

$\mathrm{(A)\ } 22 \qquad \mathrm{(B) \ }32 \qquad \mathrm{(C) \  } 34 \qquad \mathrm{(D) \  } 44 \qquad \mathrm{(E) \  }50$
The three unlabelled vertical sides have the same sum as the two labelled vertical sides, which is $10$.
The four unlabelled horizontal sides have the same sum as the one large horizontal side, which is $12$.
Thus, the perimeter is $2(12+10) = 44$, which is option $\boxed{D}$.
