Answer:

Step-by-step explanation:
Given
The attached rhombus
Required
The area

Length x is represented as the adjacent to 60 degrees
So, we have:

Solve for x


So:


At this point, we have established that the rhombus is made up 4 triangles of the following dimensions


So, the area of the rhombus is 4 times the area of 1 triangle




That quadrilateral is a parallelogram. Parallelograms have 4 sides and the opposites side are parallel to each other.
