Please help me, I am so confused, is there a formula to figure this problem out?

**MathMate**, Wednesday, September 2, 2009 at 10:48pmThe diagonal (the slant of the triangle) of a square of side x is √2*x.

Can you figure the side using this relation?

**Reiny**, Wednesday, September 2, 2009 at 10:51pmI don't know what grade level you are in, but since you seem to know about square roots, I am somewhat surprised that you don't know the Pythagorean Theorem.

Since you are dealing with a square, let each side of the square be x

then x^2 + x^2 = (4√2)^2

2x^2 = 32

x^2 = 16

x = 4

Now that we know that we have a 4 x 4 square, we can easily find its area and perimeter.
