Root rectangle photography

Because the angle between the two diagonals is 60 degrees, the length and width of the rectangle can be set to (root number 3)x (because half of the rectangle is a right triangle with angles of 30 degrees and 60 degrees), so (root number 3)x*x= (root number 3)x = 1, so the circumference of the rectangle is (1+).
