If I were not now in Scotland the answer would have been
width 7ft or
length 30yds
I know this because I was taught (while doing National Service in the RAF) how
to estimate distances. You take a point half way and estimate the shorter
distance. By applying that method enough times I was able to use a ruler to
find accurately 2^-11 of the distance. Using QPC2 to multiply that by 2048 gave
me the length required. Same for the width.
