ACT Math Prep Geometry: Area of Compound and Composite Figures
In this ACT Math prep video, we delve into Geometry and cover compound figures, which are also called composite figures. Compound figures are figures that when cut are made up of common shapes such as squares, rectangles, circles, triangles and trapezoids.
When the ACT test gives problems like this, you will usually need to find unknown sides of the figure before you can proceed to find the area. For this ACT Math example, we find missing sides of the compound figure, and then show four different ways to get the area.
