help can’t find the answer

Answer:
C.
Step-by-step explanation:
Ok I'm going to make a right triangle by drawing a straight edged line segment from the top left vertex straight down.
We can now find the height of the parallelogram.
sin(60)=h/6 (opp/hyp)
Multiply both sides by 6.
6 sin(60)=h
6*sqrt(3)/2 =h
3*sqrt(3)=h
So to find the area of the parallelogram you do base*height, so you have 8*3*sqrt(3) which simplifies to 24sqrt(3).
