Frequently asked questions
Multiply the two diagonals and halve the result: A = ½ × d₁ × d₂. Diagonals of 6 and 8 give an area of 24 square units.
The diagonals bisect each other at right angles, so each side is √((d₁/2)² + (d₂/2)²). For 6 and 8 the side is 5 units.
All four sides are equal, so the perimeter is four times one side. For diagonals 6 and 8 that is 20 units.
Yes. A square is a special rhombus whose diagonals are equal and whose angles are all right angles.
The Rhombus Calculator uses the formula: Area = Diagonal 1 × Diagonal 2 ÷ 2. For example, with diagonal 1 of 6 units and diagonal 2 of 8 units, the area is 24.0000.
