What scale factor is needed for a similarity transformation to transform a square into a square with twice the area?

1 answer

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
