The Rectangle Calculator is a simple and useful tool designed to calculate important properties of a rectangle. With just the length and width, you can find the area, perimeter, and diagonal instantly. This tool is perfect for students, teachers, architects, and anyone who works with shapes.

What Is a Rectangle?

A rectangle is a four-sided shape with opposite sides equal and all angles at 90 degrees. It is one of the most basic shapes in geometry and is widely used in real-life applications like design, construction, and mathematics.

What Can the Rectangle Calculator Do?

This calculator can quickly find:

  • Area: The space inside the rectangle (Length × Width).
  • Perimeter: The total distance around the rectangle (2 × (Length + Width)).
  • Diagonal: The straight-line distance between opposite corners (√(Length² + Width²)).

How to Use the Rectangle Calculator

Using the calculator is very easy. Just follow these steps:

  1. Enter the length of the rectangle.
  2. Enter the width of the rectangle.
  3. The calculator will show the area, perimeter, and diagonal automatically.

You can use any unit of measurement (cm, meters, inches), but make sure both length and width are in the same unit.

Why Use a Rectangle Calculator?

  • Fast and Accurate: Get correct results in seconds.
  • Helpful in Daily Tasks: Useful for construction, flooring, painting, and design work.
  • Supports Learning: Makes math easier for students.
  • No Need for Manual Calculations: Reduces time and chances of error.
