How Do You Find the Area of a Parallelogram?
In a parallelogram, opposite sides are parallel and have the same length. This applet will show you how to divide the parallelogram into pieces, arrange them together to form a rectangle, and then use the formula for the area of a rectangle to find the area of the parallelogram.
Change the size and shape of the parallelogram by dragging points A and B. Then, drag the right half of the parallelogram to form a rectangle with the left half.
Click the Start Over button, and repeat the investigation for parallelograms of other sizes.
