Regional Ratios In Regional Ratios, students find the ratio of the area of a hexagon to that of an equilateral triangle when the perimeters of the two figures are the same. It might be solved by directly calculating the areas using shape-specific area formulas, calculating the areas using the Pythagorean theorem or the properties of 30-60-90 right triangles, or by dissecting the shapes into smaller equilateral triangles. This task includes:
