The bisector of one of the corners of the parallelogram divides its side into segments

The bisector of one of the corners of the parallelogram divides its side into segments 12 and 7 cm long. find the perimeter of the parallelogram.

The bisector BM of the angle ABC forms an isosceles triangle ABM on the lateral side AB, then AB = AM = 12 cm.

Side length AD = AM + DM = 12 + 7 = 19 cm.

Since the opposite sides of the parallelogram are equal, then CD = AB = 12 cm, BC = AD = 19 cm.

The perimeter of the parallelogram is: Ravsd = 2 * (AB + AD) = 2 * (12 + 19) = 2 * 31 = 62 cm.

Answer: The perimeter of the parallelogram is 62 cm.
