Calculation:

The sides of the rectangle will be:

  $\begin{array}{l}\text{Base = BC = }\left|5-1\right|=4\\ \text{Height = }\left|3-1\right|=2\end{array}$

The area will be:

  $\begin{array}{l}A=\frac{1}{2}\left(b\right)\left(h\right)\\ A=\frac{1}{2}\left(4\right)\left(2\right)\\ A=4\text{units}\end{array}$
