WebThe area of an equilateral triangle with side length s is s²√3/4. Since we know the areas of these triangles, we can solve for their side lengths: s²√3/4=9√3. s²/4=9. s²=36. s=6. So the triangles have sides of length 6. And when follow a diameter of the circumcircle, we trace two sides of equilateral triangles.
