What is the measure of angle Y of the given parallelogram?
Given polygon is a parallelogram. We know that sum of adjacent angles in a parallelogram = 180. We can also find <ZWX using the same property, which is opposite to angle Y and will have the same value, i.e. 101 degrees.

What is the perimeter of the given parallelogram
We can also directly find out the perimeter by using the property , insteadof finding the alues of AD and AB.
perimeter = 2 x ( BC + CD)
this is possible due to the fact that opposte sides are equal in a paarallelogram.
