Ms. Sue...I understand how to get the sqrt of 420, but after that I get lost. So what you typed is not making sense in my head ..ughhh

What do you get when you multiply 20 * 21?

420, so more or less I would have had to have found 2 numbers that equaled 420 when multiplied (which product means multiply 2 numbers)correct?

So my first page would be 20

Second page would be 21
