i believe the rhombus is a square.
therefore it's are would be 12^2 = 144.

why do i believe so?

the opposite angles of a rhombus are equal.
if one of the angles is 90 degrees than the opposite anglew is 90 degrees and the adjacent angle is 90 degrees and its opposite angle is 90 degrees.

that makes it at lesst a rectangle.

all sides of a thombus are equal.

that makies it a square.
