Before electronic calculators, converting square varas (at 1 vara = 32.8748 inches) to acres was a tedious job. But if 1 vara = 33 1/3 inches, 3 varas are exactly 100 inches, 36 varas are exactly 100 feet, and 108 varas are exactly 100 yards. An easy division and some shuffling of the decimal point do the job.
Hi Emily, A mile is a unit of length and a square foot measure of area so there is no way to convert one to the other. Length and area are different concepts. There are 43,560 square feet in an acre and therefore there are 72.5 43,560 square feet in 72.5 acres. My dictionary says that hence means therefore or for this reason.
