Beta, those formulas always jumbled in my head like my buffaloes at feeding time. I remember my grandson trying to teach me, but for this farmer's heart, knowing the exact area of his field with a measuring tape is easier than with those √(x₂−x₁)²+(y₂−y₁)² puzzles. My real formula is this: if you can walk from the neem tree to the well in one hundred steps, that is your distance.
