rectangles by area in square meters

[Aigars V]

 Hi.

I have data about  areas in square meters. I want to show this data on the map as moveable rectangles (all four edges  in the same length) .
Which is the best way to do that ? Is there something similar to circle's radius for rectangles (edge length, area  ...) ?

Isn't that a square?

It's schoolbook geometry. For a given area, find the square root,
that gives the length of your sides.
To plot it on a map, you'd need some idea of where to put it.
Maybe you know the centre : then you can calculate the length of a
half-diagonal of your square. Then plot 4 points as a polygon at that
distance from your centre in NE SE SW NW directions, using the formula
for "Destination point given distance and bearing from start point"
formula at

Don't forget the visible distortion the map projection may cause for
large shapes.

Don't think so

Well, you can use an instance of Circle as a tool to make the maths
for you.

1] Set a Circle with a desired center LatLng and radius in meters.
2] Get its bounds by getBounds() method
3] Construct a Rectangle using the bounds

var radius = Math.sqrt(yourArea) / 2;
var circle = new google.maps.Circle({center: yourPoint, radius:
radius});
var bounds = circle.getBounds();
var square = new google.maps.Rectangle({bounds: bounds, map:map});
