Hi kamalakarthi,
I'm going to give you some hints so that you can retry this question on your own:
[spoiler]
1) When the GMAT gives you a 'weird' shape to work with, you should look for any opportunity to 'break down' that shape into shapes that you DO know. Here, you can break each parallelogram down into 2 right triangles and a rectangle.
2) Knowing those 60 degree angles, try breaking down each shape into a 30/60/90 right triangle and a rectangle. What would the sides of the triangle be? Use that information to figure out the dimensions of the rectangle.
3) When you have the area of one parallelogram, you just have to multiply that number by 3 to get the total area of all of the shapes.

GMAT assassins aren't born, they're made,
