Hi Martha,
You said "Wouldn't it follow that sometimes some of the 1.5
square yards will have to be wasted if the width isn't a multiple of 10
feet (for contra) or 15 feet (for English)?"
Absolutely, it is just a quick rule of thumb to get an idea
of the capacity of a hall, i.e, No you can't get 150 people doing a
dance at the same time!
I susepct a wedding party will be happy to squeeze two lines
into that space, especially if you can push the chairs back a bit to
make it slightly bigger.
And of course, for a wedding party, I wouldn't be calling
modern American contras, or what you call English Country Dancing
(Playford-style). I would be selecting simple barn dances such as you
will find at:

I'm not sure if you do this sort of stuff much in America;
when I visit I only ever seem to find contra and ECD (which is fine, as
I love both). But here in England there is a whole other stream of
social folk dance known as Barn Dance or Ceilidh.
Hope that helps.
Happy dancing,
John
