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.
