The perimeter of a parallelogram, divided into congruent parallelograms of only one form of order ( m, r ) or ( r, m ) m greater than r, r greater than or equal to one, is equal to 4m by the length of the side of shorter length of the congruent parallelograms or equals 4r by the length of the side of a greater length of the congruent parallelograms.
