More like 24 acres.
25.87 to be exact.
Damned dismal points! /sarc>
Thanks for the correction. Got in a hurry, and quick figured it at acre ~= 200X200 and 640 in a section, so 100' ~= 1/2 arce time the FULL 640, rather than the ~25/26 acres bordering the side of the section.
Sigh! 5280 X 2 X 100/43560 = what you said, and is how I should have calculated it!
