How can we find the total area of a space made up of different shapes such as rectangles, triangles, and circles?

Multiple Choice

Which of the following best describes a composite figure?

• A figure made up of only one geometric shape

• A figure made up of simple geometric shapes

• A figure with no geometric shapes

• A figure made up of only circles

Open Ended

Explain why decomposing the same composite figure in more than one way still gives the same total area.

Multiple Choice

How does understanding how to decompose composite figures help you in real-life situations, such as in architecture or design?

Multiple Choice

What are some strategies you can use to find the area of a composite figure?

• Decompose the figure into familiar shapes and use area formulas

• Estimate the area by drawing a grid

• Only use the perimeter to find the area

• Ignore the smaller shapes inside the figure

Open Ended

Explain how decomposing a composite figure into familiar shapes helps in finding its area. Provide an example from real life where this method can be applied.

Multiple Choice

Why do we divide shapes before finding the total area of a composite figure?

• To make calculations easier

• To use different formulas

• To identify familiar shapes

• To reduce errors
