16. Find the vertices and compute the area

The points $P$, $Q$ and $R$ are the mid-points of the sides $AB$, $BC$ and $CD$ of the triangle respectively. If $A$ $=$ $(0, 0)$, $B$ $=$ $(0, -12)$ and $C$ $=$ $(2, -4)$, then find the area of the triangle $PQR$.

 

Answer:

 

The area of the triangle $PQR$ $=$  square units.
