Formula
Area = d1×d2/2; Perimeter = 4×s; Height = Area/s; Side = √((d1/2)²+(d2/2)²)
- Rhombus Calculator calculates its result from Side Length (cm), Diagonal d1 (cm), Diagonal d2 (cm). It uses the formula Area = d1×d2/2; Perimeter = 4×s; Height = Area/s; Side = √((d1/2)²+(d2/2)²). Change any input to recalculate the result instantly.
- The main inputs are Side Length, Diagonal d1, Diagonal d2. Enter them in the units and format shown in the calculator.
- Keep comparable quantities in compatible units whenever the formula combines or compares them.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Rhombus
Inputs
- Side Length: 5 cm
- Diagonal d1: 8 cm
- Diagonal d2: 6 cm
Using Side Length (cm) = 5, Diagonal d1 (cm) = 8, Diagonal d2 (cm) = 6, the calculated result is 5.
