Square Calculator
Calculate area, perimeter, and diagonal of a square.
Area = s^2\nPerimeter = 4 * s\nDiagonal = s * sqrt2
Example:\nSide = 10 cm\n\nArea = 10^2 = 100 cm^2\nPerimeter = 4 * 10 = 40 cm\nDiagonal = 10 * sqrt2 = 14.14 cm
What is a square?
A 2D shape with 4 equal sides and 4 right angles (90deg). A special case of a rectangle and rhombus.
How do you find area?
Area = side * side = s^2. Example: a square with 10 cm sides has area 10^2 = 100 cm^2.
What is perimeter?
The distance around the square. Perimeter = 4 * side. Example: 4 * 10 = 40 cm.
How do you calculate diagonal?
Diagonal = side * sqrt2, using the Pythagorean theorem. Example: 10sqrt2 ≈ 14.14 cm.
What are real-world uses?
Calculating tile coverage, garden plots, room areas, fabric for square tablecloths, or flooring materials.
