Construct the Rectangle

For a web developer, it is very important to know how to design a web page’s size. So, given a specific rectangular web page’s area, your job by now is to design a rectangular web page, whose length L and width W satisfy the following requirements:

1. The area of the rectangular web page you designed must equal to the given target area.

2. The width W should not be larger than the length L, which means L >= W.

3. The difference between length L and width W should be as small as possible.
   You need to output the length L and the width W of the web page you designed in sequence.

var constructRectangle = function(area) {    var res = [];    var b;    var a = parseInt(Math.sqrt(area));    while(area % a != 0){      a--    }    b = area/a;    res[1] = a;    res[0] = b;    return res;};
