Area & Perimeter of a Rectangle

Directions: Using the digits 1-9 at most once each, create a rectangle with an area as close to 500 and a perimeter as close to 100 as possible.


The perimeter is the distance around the outside; and the area is the space inside. How does changing just one dimension affect the area/perimeter?  What patterns do you notice?  
Could you ever have a perimeter of 101 or 99?
