In triangle $LMN$, $PQ \ || \ MN$, and $P$ and $Q$ are mid-points of $LM$ and $LN$, respectively. If $MP$ $=$ 6 $cm$, $LN$ $=$ 17 $cm$ and $PQ$ $=$ 6 $cm$, find the following:

 

 

(i) The length of $LM$ $=$  $cm$

 

(ii) The length of $MN$ $=$  $cm$

 

(iii) The perimeter of $\Delta LMN$ $=$  $cm$
