Area of Square Calculator

Calculate the area, perimeter, and diagonal of a square by entering the side length. This tool provides instant results with precise calculations for all square properties.

How to Use the Square Calculator

1. Enter the length of one side of the square in the input field
2. Click the "Calculate" button to get instant results
3. View the calculated area, perimeter, and diagonal values
4. All calculations are performed using standard geometric formulas

Square Formulas

The calculator uses the following formulas to compute square properties:

• Area: A = s² (side length squared)
• Perimeter: P = 4s (four times the side length)
• Diagonal: d = s√2 (side length times the square root of 2)

About Squares

A square is a regular quadrilateral with four equal sides and four right angles (90°). It is both a rectangle and a rhombus, making it a special case of both shapes. Squares have rotational symmetry of order 4 and four lines of reflective symmetry.
