If you have 100 pennies and you are suppose to make an array do you arrange the pennies by date?

Hi Saundra,

If the only instructions were to make an array then I think you are expected to put them in a rectangular array. There are many ways to do this, and I expect that this is the reason you were asked to do it. You might have 2 rows of 50 pennies each or 25 rows of 4 pennies each or ...

How many different rectangular arrays can you make?
