### Area of Composite Rectangles Worksheets

In these free math worksheets, you will learn how to find the area of figures or shapes that are composed of rectangles. Find areas by decomposing into rectangles or completing composite figures to form rectangles.

How to solve the area of composite rectangles?
To find the area of composite rectangles, which are shapes made up of multiple rectangles, you’ll need to break down the composite figure into its individual rectangles, calculate the area of each rectangle, and then add or subtract the areas as needed.

1. Identify the Composite Shape:
Understand the overall shape and identify the rectangles that make up the composite figure.
2. Decompose into Rectangles:
Break down the composite shape into its constituent rectangles. This may involve drawing lines to create separate rectangles within the figure.
3. Label the Dimensions:
Label the length and width of each individual rectangle. Use variables or specific values provided in the problem.
4. Calculate the Area of Each Rectangle:
Use the area formula (A=length×width) to find the area of each individual rectangle. Perform this calculation for each rectangle in the composite figure.
5. Add or Subtract Areas:
Determine whether you need to add or subtract the areas of the individual rectangles based on the composite shape.
