Math Module - Finding the Area of a Parallelogram (Pptx)

Finding the Area of a Parallelogram

A parallelogram is a quadrilateral where the opposite sides are congruent and parallel.
A rectangle is a type of parallelogram, but we often see parallelograms that are not rectangles (parallelograms without right angles).

Side AC has the same length as side BD.
Side AB has the same length as side CD.

Any side of a parallelogram can be considered a base.  The height of a parallelogram is the perpendicular distance between opposite bases.
The area formula is A=bh

How do we find the area of a parallelogram?
Remember :
    To find the area of a parallelogram, use the formula
A = b x h
