The perimeter of a parallelogram divided into congruent parallelograms in the way two and three way to order ( m, r ) or ( r, m ) m greater than r, r greater than or equal to one, is equal to 2 that multiplies the sum of m by the length of the shorter length of the congruent parallelograms side more r by the length of the side of a greater length of the congruent parallelograms.
