Description

This image shows a composite figure made up of a rectangle and a circle connected by a long, thin rectangle. This configuration might represent various real-world objects, such as a lollipop, a simplified key, or certain types of tools or instruments.

To find the total area of this figure, we would add the areas of the rectangle (l * w), the circle (πr²), and the connecting thin rectangle. The perimeter calculation would involve the circumference of the circle and the outer edges of the rectangles, excluding any parts where they connect.

This composite figure is excellent for teaching students about combining different geometric shapes and how to approach area and perimeter calculations for more complex figures. It also provides an opportunity to discuss practical applications of geometry in everyday objects.

Teacher's Script: "Examine this interesting shape. How would you break it down to calculate its area? What challenges might you face in determining its perimeter? Can you think of any objects in real life that have a similar shape? How might understanding this type of composite figure be useful in design or engineering?"
