Rhombus from diagonals
Use the perpendicular diagonals of a rhombus to find its area; their half-lengths form a right triangle that determines each side and the perimeter.

How to calculate
Calculate the area of a kite from its two perpendicular diagonals; the diagonals alone do not determine its perimeter.
Area = a*b/2 units²
Worked example
First diagonal: 6; Second diagonal: 10.
Area: 30 units².
Assumptions and limits
Calculate the area of a kite from its two perpendicular diagonals; the diagonals alone do not determine its perimeter. Use the same length unit throughout. Angles marked degrees use degrees. Results describe ideal geometric shapes.
Results are rounded for display; calculations use unrounded values. Read our calculation methodology.
