📝 Question: Rectangle Area Calculator Web App




You are required to create a simple Rectangle Area Calculator using

HTML and JavaScript. The application should allow users to input

the length and breadth of a rectangle, and upon clicking a button,

it should calculate and display the area.



📁 Files Provided:





index.html – The HTML structure of the application.



script.js – A separate JavaScript file linked to index.html to handle the functionality.



✅ Your Task Is to:


🔹 In index.html:



Create a form-like layout that includes:



A labeled input field for length (number input).

A labeled input field for breadth (number input).

A button labeled "Calculate Area".

A <div> element with id="result" where the calculated area will be displayed.





Link the external JavaScript file script.js just before the closing </body> tag.



🔹 In script.js:



Write JavaScript code to:



Get the values entered for length and breadth.

Calculate the area using the formula:


Area = length × breadth



Update the text inside <div id="result"> to display the calculated area.





Ensure the calculation is triggered only when the user clicks the "Calculate Area" button.



💡 Additional Notes:



Use DOM methods like document.getElementById() or querySelector() to access and update elements.

Validate inputs: If either field is empty, zero, or not a number, show an appropriate error message in the result div.

Styling is optional but may be rewarded if time permits.





🧪 Example:

User enters:



Length: 5



Breadth: 4





On clicking "Calculate Area", the output should be:

Area of Rectangle: 20
