Area of Composite Shapes
Piece by Piece
Can't find the area formula for a particular shape on the GED® Formula Sheet? Don't panic. Break the shape into pieces that you do have a formula for.
STEP 1: WATCH THE VIRTUAL CLASS VIDEO AND TAKE NOTES
Make sure to note the following:
Composite shapes are composed, or built, of known shapes. For example, two rectangles can be put together to form an "L-shape", a triangle stacked on a rectangle forms a "house shape", and a semi-circle balanced atop an isosceles triangle looks a lot like an "ice cream cone". The area of a composite shape is found by adding and/or subtracting the areas of the composite pieces.
Refer to your GED Formula sheet and print out the example problems to follow along with the video lesson.
Do you have a question about the class video, practice, or example problems? Post a picture to our FB group for immediate assistance. Be sure to include the lesson name and level in your post.
