Area of Composite Figures

This page presents a detailed explanation and example of calculating the area of composite figures, which is an essential skill for middle school mathematics. The worksheet provides a clear definition, step-by-step instructions, and a practical example to help students understand and apply the concept.

Definition: A composite figure is a shape made up of simple geometric shapes.

The process for finding the area of a composite figure involves two main steps:

1. Identify the different shapes within the figure and create distinct lines to separate them.
2. Calculate the area of each individual shape and sum them up to get the total area.

Example: The worksheet includes a composite figure consisting of a rectangle and two triangles.

The example problem walks through the calculation process:

1. Divide the composite figure into its component shapes (one rectangle and two triangles).
2. Calculate the area of each shape separately:
   • Rectangle: 20 ft × 12 ft = 240 ft²
   • Triangle 1: (3 ft × 4 ft) ÷ 2 = 6 ft²
   • Triangle 2: (3 ft × 6 ft) ÷ 2 = 9 ft²
3. Sum up the individual areas: 240 ft² + 6 ft² + 9 ft² = 255 ft²

Highlight: The final answer shows that the total area of the composite figure is 255 ft².
