10-72.

On graph paper, draw a rectangle with side lengths of $15$ units and $9$ units. Reduce the rectangle by using a scale factor of $\frac { 1 } { 3 }$. Then determine the area and perimeter of both rectangles.

Make sure to shrink the rectangle, not make it bigger.
Draw both rectangles to make it easier.

original rectangle's perimeter $= 48$ units
