Diamond (Rhombus)
Calculate the area and perimeter of a diamond.
This calculator uses feet and or inches for measurements.
A diamond (rhombus) is a four-sided shape where all four sides are the same length, and the opposing angles are equal. If the angle is 90 degrees, it is a square.
Note:
The angle can not be more than 180°
