Which approach did Al-Khwarizmi’s algebra enable surveyors to accurately determine land area when parcel shapes are irregular polygons?

💡 Explanation

Al-Khwarizmi's algebra enabled surveyors to decompose irregular polygons into simpler shapes like triangles and rectangles, because algebraic techniques provide tools to calculate each area and summing the results accurately. Therefore, decomposition into basic geometrical forms results, rather than using triangles, averages, or circles which are less versatile.
