Here's a hint: the square root of 420 is 20.49

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?

Math/Algebra  Angel Eyes, Friday, August 20, 2010 at 8:43pm
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

Math/Algebra  Ms. Sue, Friday, August 20, 2010 at 8:50pm
Right.
