Description

This image illustrates a composite figure composed of one rectangle and one semicircle. This combination of shapes is often seen in architectural designs and mechanical parts.

To calculate the total area, we would add the areas of the rectangle (l * w) and the semicircle (πr² / 2, where r is half the width of the rectangle). The perimeter calculation would involve the straight edges of the rectangle and the curved edge of the semicircle.

This figure demonstrates how combining simple shapes can create more complex and functional designs. It's an excellent example for teaching students about area and perimeter of composite figures, as well as the practical applications of geometry in design and engineering.

Teacher's Script: "Examine this composite figure. How would you break it down to calculate its area? Can you think of any real-world objects that have a similar shape? How might understanding this shape be useful in fields like architecture or product design?"
