Good old Pythagoras!
"The square of the hypotenuse (diagonal) is equal to the sum of the square
of the other two sides".
Square the two sides of the rectangle (multiply the distance by itself - in
your example, it would be 20' x 20' and 30' x 30') and add the resulting
figures together. so, 20' x 20' plus 30' x 30' = 400 + 900 = 1300. Then find
the square root of the answer (36.055 your calculator should have a square
root button!) which is the length of the diagonal. Then use the arch length
formulae to find the length of the arch or swag itself.
As to the width of the columns, it does depend on which method you are going
to use, and how the balloons are packed together. If you are using alternate
size square pack, for instance, the EFFECTIVE width of the column will be
less than the actual width because of the way the columns interlock. As far
as I know, there are no formulas for calculating this. Sometimes low-tech is
best - and I agree fully with building a bit and measuring!!
