Calculate the perimeter of the parallelogram ABCD, given that CD is parallel to AB.
Calculate the perimeter of the parallelogram ABCD, given that CD is parallel to AB.
First we need to remember that pairs of opposite sides in a parallelogram are parallel and equal.
Therefore, AB is parallel to CD and BC is parallel to AD.
From this we can conclude that AB = CD = 7.
Also: BC = AD = 12.
Finally we can calculate the perimeter by adding all the sides together:
