Rhombus area calculator tool is used to calculate area and perimeter of a rhombus, enter the length of the base (b) and height of the altitude (h) for calculations.

Area=base (b) x height (h)

Perimeter=4 x base (b)

A quadrilateral, all sides are equal in length, and opposite sides are parallel. The attributes indicate that a rhombus can also be classified as a parallelogram and all parallelograms are also classified as a trapezoid. The diagonals of a rhombus bisect one another but because they bisect each other at 90° angles, we call these diagonals perpendicular bisectors.

Area=b x h

Perimeter=4b

- Opposite sides are congruent (they equal each other).
- Opposite angles are congruent (they equal each other).
- Consecutive angles are supplementary (they add up to 180).
- Diagonals bisect each other (the parts are equal).
- Diagonals perpendicular (the form right angles in the middle).
- Diagonals bisect angles (the angles are equal to each other).
- All four sides are congruent.
- The diagonals are NOT congruent.
