i think it’s 243 root 3

if it’s a regular triangle, then all angles equal 60°. you can find the base of the triangle by using the 30 60 90 ratio and imagining a right triangle. if you use that you find that the base of the triangle is 18 root three, and the distance from the dot to the base is 9. to get the height of the whole triangle you add 9 to 18 = 27. to find the area

1/2(27*18root3)=243root3
