## Algorithm

We know the basic formula to get area and peremeter of a rectangle.

Formulas:

Area of a rectangle = length * width

Peremeter of a rectangle = 2 * ( length + width )

## Code Examples

### #1 Code Example with Javascript Programming

Code - Javascript Programming

/**
*   Calculate the area of a rectangle.
*
*   length: The length of the rectangle.
*   width: The width of the rectangle.
*
*	Return a number denoting the rectangle's area.
**/
function getArea(length, width) {
let area;

area = length * width;

return area;
}

/**
*   Calculate the perimeter of a rectangle.
*
*	length: The length of the rectangle.
*   width: The width of the rectangle.
*
*	Return a number denoting the perimeter of a rectangle.
**/
function getPerimeter(length, width) {
let perimeter;

perimeter = 2 * ( length + width );

return perimeter;
}
