**JJ**, Thursday, February 21, 2013 at 5:51pmA square with an area of 4 has to have all sides equal to 2. Right?

If I increase by a factor of k that means multiply 2 times k

My area is 2k times 2k = 4k^2

I would set this equal to 9

I am getting 3/2 for the value of k

-3/2 is another possibility, but we have to discount it because we don't measure distance as negative numbers.

I agree with your 3/2, but I wonder if someone else summed -3/2 and 3/2 = 0
