Here is bens reasoning for finding the upper and lower boundaries in which the actual area of his garden plot lies plot lies. Given measurements for length l and width w, the actual length is l + /-e and the actual width is w +/- e where e is the absolute error in each length measurement. So, the actual area lies between (l-e)(w-e) and (l+e)(w+e) i.e., between lw – e(l+w)+e2 and lw+e(l+w)=e2 .But e2 is negligible compared with other terms, so the actual area is lw+/-(w+l)e. Is his argument valid?
