Diskusi Concepts
1. Go through solutions for questions from the Development stage: 2. Question: Calculate the area of a regular hexagon with a side of 8 cm. 3. Solution: For this, we use the formula: A = (3√3/2) * L², where L is the side length. 4. Calculation: A = (3√3/2) * 8² = (3√3/2) * 64 = 96√3 cm². 5. Question: If six equilateral triangles form a hexagon, and the area of each triangle is 12 cm², what is the total area of the hexagon? 6. Solution: Total area of the hexagon is the sum of the areas of the six triangles. 7. Calculation: Total area = 6 * 12 = 72 cm². 8. Question: For a hexagon-shaped room with each side being 5 meters, how do you find the total area? 9. Solution: We apply the hexagon area formula: A = (3√3/2) * L². 10. Calculation: A = (3√3/2) * 5² = (3√3/2) * 25 = 37.5√3 m².
Engaging Students
1. Question: Why is it important to know the area of a hexagon in real life? List some examples. 2. Reflection: How might the geometry of hexagons be relevant in other fields, like architecture or biology? 3. Question: What is the total area of 30 hexagonal bee cells, each with a side of 1 cm? 4. Reflection: If you were designing a hexagon-shaped floor for a room, how would properties of the hexagon affect your material and design choices?
