Write a program to Find the Perimeter of a Rectangle in JavaScript

Create a function that takes length and width and finds the perimeter of a rectangle.
 
Examples
findPerimeter(6, 7) ➞ 26
findPerimeter(20, 10) ➞ 60
findPerimeter(2, 9) ➞ 22
 
Note: we will make a function findPerimeter which will take two parameters i.e height and width of rectangle. To calculate the perimeter of rectangle we will use formula
perimeter = 2 x height x width;
<script>
function findPerimeter(length, width){
var perimeter = 2 * length * width;
return perimeter;
}
var length = 23;
var height = 10;
//calculate the perimeter
var perimeter = findPerimeter(length, height);
console.log(perimeter); // this will print 460 in console.
</script>
