How to Calculate Square
What is Square?
A square calculator computes area (s²), perimeter (4s), diagonal (s√2), and other properties of a square with side length s. Squares are special rectangles with all sides equal and all angles 90°.
Step-by-Step Guide
- 1Area = s² (side length squared)
- 2Perimeter = 4s
- 3Diagonal = s√2 ≈ 1.414s
- 4Inscribed circle radius = s/2; Circumscribed circle radius = s√2/2
Worked Examples
Input
Side = 5
Result
Area = 25, Perimeter = 20, Diagonal = 7.071
Input
Area = 64
Result
Side = 8, Perimeter = 32
s = √64 = 8
