a = lenght of first square
b = lenght of second square
A1 = Area of first square
A2 = Area of second square
A1 = a^2
A2 = b^2
A1 / A2 = 2
a^2 / b^2 =2
a/b = square root of 2 = 1.41421
b = lenght of second square
A1 = Area of first square
A2 = Area of second square
A1 = a^2
A2 = b^2
A1 / A2 = 2
a^2 / b^2 =2
