Plot the points $A\left(5, 3\right)$, $B\left(−4, 3\right)$, $C\left(−4, −6\right)$, and $D\left(5, −6\right)$ on a set of axes. Connect the points in order. Then connect D to A to form a quadrilateral (a polygon with four sides).  

1. What kind of quadrilateral was formed?

   Hint (a):

   Are there any congruent sides or angles?

2. How long is each side of the quadrilateral?

   Hint (b):

   Count the number of boxes from side to side.

3. What is the area of the quadrilateral?

   Hint (c):

   $\text{Area} = \text{base } x \text{ height.}$

4. What is the perimeter of the quadrilateral?

   Hint (d):

   Perimeter = sum of the side lengths.
