Which shapes could this hexagon be decomposed into to find its area? Choose all that apply (3 points).
Scilla [17]
You can do:

-two trapezoids
-six triangles
-two parallelograms

You can't put it into one rectangle, that will definitely not work. 

As you can see from the attachment, triangles work, trapezoid as well, and two parallelograms. The one rectangle would not work.

I hope this helps!
