Rectangle Diagonal Result

The diagonal of a rectangle is a fundamental concept in geometry. Whether you are working on a school project, designing a room, or involved in construction work, knowing how to calculate the diagonal is essential. Manually calculating can be time-consuming, especially if you want to avoid errors. That’s where the Diagonal of a Rectangle Calculator comes in.

This easy-to-use tool instantly computes the diagonal of a rectangle using the Pythagorean theorem. With just two inputs—length and width—you’ll receive an accurate diagonal measurement, along with a step-by-step breakdown of the calculation.

How the Diagonal of a Rectangle Calculator Works

The diagonal of a rectangle is the line connecting opposite corners. According to the Pythagorean theorem:

[
Diagonal = \sqrt{(Length^2 + Width^2)}
]

The calculator automates this formula for you. By entering the rectangle’s length and width, it squares both values, adds them, and then finds the square root to provide the diagonal.

Step-by-Step Instructions

Here’s how you can use the calculator:

  1. Enter the Rectangle’s Length
    • Type the length value in the first field.
    • Make sure it’s a non-negative number.
  2. Enter the Rectangle’s Width
    • Add the width value in the second input field.
  3. Click “Calculate”
    • The tool will display a progress animation before showing results.
  4. View the Results
    • You’ll see the diagonal formula, the calculated value, and the full step-by-step solution.
  5. Optional Actions
    • Copy the results to your clipboard.
    • Share results directly with others.
  6. Reset if Needed
    • Use the reset button to clear all inputs and start over.

Practical Example

Let’s say you want to calculate the diagonal of a TV screen:

  • Length: 40 inches
  • Width: 30 inches

Step 1: Square the length → 40² = 1600
Step 2: Square the width → 30² = 900
Step 3: Add the squares → 1600 + 900 = 2500
Step 4: Find the square root → √2500 = 50 inches

The diagonal of the screen is 50 inches, which means the screen size can be advertised as a 50-inch TV. The calculator will display the same process automatically.
