Google Maps Javascript. How to convert lat,lng to north,south,east,west coordinates?

Question

JavaScript

Hello. I create a groundLayout. But there are only lat and lng coordinates. And when creating a goundLayout, you need to specify the coordinates of all 4 sides. How can I convert my values ​​​​to the right ones? Thank you!

var imageBounds = {
    lat: 55.558322,
    lng: 37.556446
};

var historicalOverlay = new google.maps.GroundOverlay('https://www.lib.utexas.edu/maps/historical/newark_nj_1922.jpg',imageBounds);

historicalOverlay.setMap(map.map);

And you yourself do not think that you are citing too little source data. It's like there is a side of a rectangle, how to find its perimeter.
You also have image dimensions, width and height. You just have to calculate the pixel size of this image. If it's scientific. And so estimate for yourself where the left border of the picture passes, where the top one, etc. - thus you pull it crookedly, but pull it over the globe :)
