How do you find the area and perimeter of a parallelogram with vertices at points (-6,-5), (-2,4), (5,4), and (1, -5)?
Please see the explanation.
Let's move everything to the right 6 and up 5; this makes the vertices become:
Let side AD be the base of the parallelogram; it runs along the x axis for 7 units, therefore, this is the length of the base, b.
Point B is 9 units above side AD, therefore, this is the height.
The length of side AB is:
