# Day 1: Arithmetic Operators (10 Days of Javascript)

Complete the following functions in the editor below:

1. `getArea(length, width)`: Calculate and return the area of a rectangle having sides length and width.
2. `getPerimeter(length, width)`: Calculate and return the perimeter of a rectangle having sides length and width.

The values returned by these functions are printed to stdout by locked stub code in the editor.

Solution:

``````'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++];
}
