Then the circumference of rectangular ABCD is AB+BC+CD+AD=a+2a+a+2a=6a.
? The circumference of rectangular ABFE is AB+BF+EF+AE=4a.
? Rectangular ABFE perimeter =2/3? Rectangular ABCD perimeter
Perimeter of rectangular MBFN = 1/2? Rectangular ABCD perimeter
In the nth segmentation, n>3;
If n is an odd number, the perimeter of the rectangle is {6 * (2/3 * 3/4) (n-1)} * 2/3 = (1/2) (n-3).
If n is an even number, the circumference of the rectangle is 6 * (2/3 * 3/4) n = 3 * (1/2) (n-1).
