# Day 4: Create a Rectangle Object | 10 Days of JavaScript – Hacker Rank Solution

Day 4: Create a Rectangle Object | 10 Days of JavaScript – Hacker Rank Solution: Hey Guy’s In this post we are solving Day 4: Create a Rectangle Object which is a part of 10 Days of JavaScript Series.

## Objective

In this challenge, we practice creating objects. Check out the attached tutorial for more details.

Complete the function in the editor. It has two parameters: a and b. It must return an object modeling a rectangle that has the following properties:

• length: This value is equal to a.
• width: This value is equal to b.
• perimeter: This value is equal to 2 x (a + b)
• area: This value is equal to a x b

Note: The names of the object’s properties must be spelled correctly to pass this challenge.

## Input Format

The first line contains an integer denoting a.
The second line contains an integer denoting b.

## Constraints

• 1 <= ab <= 100

## Output Format

Return a object that has the properties specified above. Locked code in the editor prints the returned object’s lengthwidthperimeter, and area to STDOUT.

Sample Input 0

4

5

Sample Output 0

4

5

18

20

Explanation 0

Given a length of a = 4 and a width of b = 5, the Rectangle object’s perimeter is 4 + 4 + 5 + 5 = 18 and its area is 4 x 5 = 20.

```'use strict';
process.stdin.resume();
process.stdin.setEncoding('utf-8');
let inputString = '';
let currentLine = 0;
process.stdin.on('data', inputStdin => {
inputString += inputStdin;
});
process.stdin.on('end', _ => {
inputString = inputString.trim().split('\n').map(string => {
return string.trim();
});
main();
});
return inputString[currentLine++];
}
/*
* Complete the Rectangle function
*/
function Rectangle(a, b) {
this.length = a;
this.width = b;
this.area = a * b;
this.perimeter = 2 * (a + b);
}
function main() {
const a = +(readLine());
const b = +(readLine());
const rec = new Rectangle(a, b);
console.log(rec.length);
console.log(rec.width);
console.log(rec.perimeter);
console.log(rec.area);
}```
