2-83.

Plot $ABCDE$ with vertices $A(–3, –2), B(5, –2), C(5, 3), D(1, 6), \text{and}\ E(–3, 3)$ on graph paper.

1. Use the method from problem 2-47 to enlarge it from the origin by a factor of 2. Label the image $A^\prime B^\prime C^\prime D^\prime E^\prime$

2. How are the coordinates of the vertices of $A^\prime B^\prime C^\prime D^\prime E^\prime$ related to the coordinates of the vertices of $ABCDE$?

3. What are the area and the perimeter of both figures?

Perimeter of $ABCDE=28$ units

Use the eTool below to plot the points and enlarge the figure.
