The following perpendicular offsets were taken at 10 m intervals from a survey line to an irregular boundary line. The area in square metre enclosed between the survey line, irregular line, first and last offsets by Simpson's rule is: Perpendicular offsets, 5 m, 2 m,4.5 m, 6 m, 1 m,2 m,4 m, 2.5 m, 4 m
A260 m²
B520 m²
