Square Formulas
Area of a Square
The area is the total space inside a square.
Formula
Area = Side × Side
or
Area = Side²
Perimeter of a Square
The perimeter is the total distance around the square.
Formula
Perimeter = 4 × Side
Diagonal of a Square
The diagonal is the straight-line distance between two opposite corners.
Formula
Diagonal = Side × √2
How to Use the Square Calculator
Using the calculator is simple.
- Enter the side length.
- Click the Calculate button.
- Instantly view the area, perimeter, and diagonal.
Some calculators also allow you to calculate the side length from the area or perimeter.
Example Calculation
Suppose the side length is 10 ft.
Results:
- Area = 100 square feet
- Perimeter = 40 feet
- Diagonal ≈ 14.14 feet
The calculator performs these calculations automatically.
Properties of a Square
A square has several unique geometric properties.
- All four sides are equal.
- All four interior angles are 90°.
- Opposite sides are parallel.
- Diagonals are equal.
- Diagonals bisect each other at right angles.
- A square is both a rectangle and a rhombus.
These properties make the square one of the most important shapes in geometry.
