Let the side of the square be x.
x^2+x^2=130^2
2x^2=130*130
x=130/√2=91.923
The length of the side is 91.923.

Pythagoras:
The square of the hypotenuse is equal to the sums of the squares of the sides. And our sides are the same length because it's a square, so we will call our sides "s"
Add s on right
Divide both sides by 2

Do the math in your calculator and you get:

Let's take the square root of both sides to get rid of the exponent:
91.9= s Each of the sides measures 91.9
