Diskusi Konsep

1. Detailed breakdown of the solutions from the Development stage: 2. Question: What is the area of a regular hexagon with a side length of 8 cm? 3. Solution: To compute the area of a regular hexagon, we use the formula: A = (3√3/2) * L², where L is the length of a side. 4. Calculation: A = (3√3/2) * 8² = (3√3/2) * 64 = 96√3 cm². 5. Question: If six equilateral triangles form a hexagon and each triangle has an area of 12 cm², what is the hexagon’s total area? 6. Solution: The total area of the hexagon is the sum of the areas of six equilateral triangles. 7. Calculation: Total area = 6 * 12 = 72 cm². 8. Question: A hexagonal room has each side measuring 5 meters. What is the total area of the room? 9. Solution: We utilize the formula for the area of a regular hexagon: A = (3√3/2) * L². 10. Calculation: A = (3√3/2) * 5² = (3√3/2) * 25 = 37.5√3 m².
