Let \(\mathbf{p} = \begin{pmatrix} 2 \\ 4 \end{pmatrix}\), \(\mathbf{q} = \begin{pmatrix} -3 \\ 1 \end{pmatrix}\), and \(\mathbf{r} = \begin{pmatrix} 1 \\ -3 \end{pmatrix}\). Find the area of the parallelogram with vertices \(\mathbf{0}, \mathbf{p}, \mathbf{q},\) and \(\mathbf{p} + \mathbf{q}\). Then, find the area of the triangle formed by \(\mathbf{q}, \mathbf{r},\) and \(\mathbf{q} + \mathbf{r}\).
