1. In accordance with the properties of the parallelogram, the bisector AE separates the triangle from it
ABE, two sides of which are equal:
AB = BE = 7 centimeters.
2. BC = BE + CE = 7 + 3 = 10 centimeters.
3.Calculate the perimeter of the parallelogram (P), taking into account that the sides of this geometric
the figures opposite each other are equal:
P = 2 (BC + AD) = 2 x (10 + 7) = 34 centimeters.
Answer: P = 34 centimeters.
