1. Stating the problem: Generate a similar exercise involving a composite figure made of a rectangle and two semicircles but with different measurements. 2. Original figure details: Rectangle with length 12 m and width 6 m. Left semicircle radius: 6 m. Right semicircle radius: 8 m. 3. New exercise: Consider a rectangle with length 15 m and width 7 m. On the left side of the rectangle, a semicircle with radius 7 m extends outward. On the right side of the rectangle, a semicircle with radius 9 m extends downward. Points A, B, C, D, and E define the perimeter of the figure. 4. Important rules: The semicircle radius corresponds to the width of the rectangle side it is attached to. 5. This exercise can be used to calculate perimeter, area, or other properties of the composite figure. Final generated exercise: "Consider a rectangle with length 15 meters and width 7 meters. On the left side of the rectangle, a semicircle with radius 7 meters extends outward. On the right side, a semicircle with radius 9 meters extends downward. Points A, B, C, D, and E define the perimeter of the figure."
