Suggestion:
Since brick hangers may not be commonplace.
Take a picture of front of plane from as far a distance as possible with
contrast background. Use a telephoto lens to get a tight shot with least
angular distortion. (This applys more to a canard because winglets would show
as much wider)
Load picture into AutoCAD
Scale image until equal to wingspan.
Use AREA function to trace around image.
Alternative, find 3-view, scan in and do same routine.
Final alternative, do as we do in Naval Architecture and print image as large
as possible, trace around image with a planometer, apply scale factor and you
get the area.
