You will be creating a 45-45-90 triangle in which the hypotenuse is the leg multiplied by the square root of 2

You will have two isosceles right triangles after the fold. The hypotenuse is the longest side of a right triangle. In the case of the 45-45-90 triangle, the hypotenuse is square root of 2 times a leg of the triangle. So, 20 times square root of 2 = 28.3 cm --> answer approximate. You can also solve for the length by solving the equation x^ + x^2 = 20^2.
