Area of a Rectangle

Good Evening

What's the best way to calculate the area of a rectangle created with
the Google map api Drawing Manager?

A rectangle is a four sided polygon. You should be able to do it the
same way as you do it for polygons. You will need to calculate the
path (the four corners).

If the rectangle is large, you may need to account for the curvature
of the earth - do you want the area of the surface or the imaginary
plane rectangle?

Based upon the method used in my site to calculate polygons using the geometry library: 

 polygonArea = google.maps.geometry.spherical.computeArea(mapPolygon.getPath());

There is no "getPath()" method for the google.maps.Rectangle class to find the path of the rectangle drawn with the Drawing Manager.

No. But pretty trival it make one yourself.

Get the bounds, from that get coordinates of opposing corners. Use
them to build a new circular path.
