Understanding Composite Figures

What are composite figures?

• Irregular 2D figures made from basic shapes

• 3D shapes made from basic shapes

• Regular 2D figures made from complex shapes

• Simple geometric shapes

How do you find the area of a composite figure?

• Multiply the dimensions of the figure

• Divide the figure into basic shapes and sum their areas

• Use the Pythagorean theorem

• Measure the figure with a ruler
