The square root of 225 is 15.
Perimeter = 4s
P = 2L + 2W

I don't get it though can you be more specific?

What about the second one?

Math  Ms. Sue, Monday, February 25, 2013 at 6:36pm
This makes me wonder how you got your answers.
You got 15 for the sides of the first one. For a square, you get 15 by taking the square root of the area.
In the second one, the perimeter is 400.
400/4 = 100
