(Approximately) ##4046.83 “sq.m.”/”acre”##
##1## mile ##= 1,609.34## meters
(from here on I used a calculator)
##1 ” sq. mile “= (1,609.34)^2 = 2,589,975.24 ” sq. meters”##
##(1 ” sq. mile”)/(640 ” acres”)##
##color(white)(“XXX”)=(2,589,975.24 ” sq. meters”)/(640 ” acres”)##
##color(white)(“XXX”)=(4046.83 ” sq. meters”)/(1 ” acre”)##
