Side from diagonals of a Rhombus
a = ½√(d₁² + d₂²)
Where: a = side, d₁ = d₁, d₂ = d₂
Use the same units for all lengths (e.g. all in cm); areas come out in cm², volumes in cm³.
Solved example
Given: d_1 = 7, d_2 = 5
Find: a (side)
- Formula: a = √(d₁² + d₂²)/2
- Substitute the values: a = √(5² + 7²)/2
- Result: a = 4.301163
Answer: a = 4.301163
