Area of trapezoids

VIDEO 4:48 minutes
A trapezoid is a cousin of the parallelogram. However, in trapezoid only two of the opposing sides are parallel to each other. Here's we explain how to find its area.

Finding area by rearranging parts

VIDEO 3:57 minutes
Sometimes it helps to rearrange the parts of geometric figures to find the area. That's what we're going to do here.

Area of composite shapes

VIDEO 5:15 minutes
Don't be intimidated by odd looking geometric figures and being asked to find its area. In this example you'll understand that breaking up the figure into smaller geometric shapes that are regular make the task a lot easier.

Area of composite shapes

PRACTICE PROBLEMS
Practice finding the areas of complex shapes that are composed of smaller shapes.

Area challenge
