Eight cubits is a half foot larger than 11½ feet. Perhaps the difference reflects the standardization of an old unit by the British administration.
েলাচা … a measure of land containing four square yards [caution, incorrect-ed.] or one-hundreth part of a bighā.

The definition stumbles on the difference between four yards square (that is, an area of 16 square yards) and four square yards. The Assamese bighā is 1600 square yards. One-hundreth of that is 16 square yards, or 4 yards square, or 8 cubits square.
