Area of Composite Figures
Calculating the area of complex shapes by decomposing them into simpler geometric figures.
Key Questions
- Differentiate strategies for finding the area of composite figures (decomposition vs. subtraction).
- Design a method to calculate the area of an irregularly shaped object.
- Evaluate the efficiency of different decomposition strategies for a given composite figure.
