# 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.

## STEP 2: COMPLETE ONE LEVEL OF PRACTICE

Area of Shapes Composed of Rectangles

### ALL LEVELS

Find the area of compound shapes composed entirely of rectangles.
