ABCD – parallelogram. BO is the bisector of angle B, which divides the side of blood pressure into segments equal to 4 cm and 10 cm, counting from point B. Find the perimeter of the parallelogram of ABCD.
AD = BC = 10 + 4 = 14cm
Angle ABO = Angle CBO (BO-Bisector)
Angle CBO = angular BOA (cross-lying at BC || AD – hence angular ABO = angular BOA and triangular ABO-isosceles
AO = AB = CD = 10cm
P = 2 (14 + 10) = 48
