Question : What is the area of the parallelogram ABCD?
Area of Parallelogram = Base * Height
We already have Base = 8 so we only need the Height of the Parallelogram i.e. perpendicular distance between AB and CD
Statement 1: The sum of Angle C and Angle B is 180°
This is a fact about any parallelogram hence Options A C D may be eliminated only options B and E remain
NOT SUFFICIENT
Statement 2: The shortest possible distance from point A to line segment DC is 10.
i.e. Height = 10 hence
Area of parallelogram = 8*10 = 80
SUFFICIENT
Answer: Option B

Can we consider the height as 90 degrees because it says that the shortest distance from point A to line segment DB in this case is always going to be at 90 degrees?
