--description--

By counting carefully it can be seen that a rectangular grid measuring 3 by 2 contains eighteen rectangles:

Although there exists no rectangular grid that contains exactly two million rectangles, find the area of the grid with the nearest solution.

--hints--

countingRectangles() should return a number.

assert(typeof countingRectangles() === 'number');

countingRectangles() should return 2772.

assert.strictEqual(countingRectangles(), 2772);

function countingRectangles() {

  return true;
}

countingRectangles();

// solution required
