Using Simpson's one third rule, what area is obtained from five equally spaced offsets of 2 m, 4 m, 6 m, 5 m and 3 m at 10 m intervals?
Correct answer: C. 176.67 m²
- A. 160.00 m²
- B. 166.67 m²
- C. 176.67 m²
- D. 186.67 m²
Explanation
The area is (10/3)[2 + 3 + 4(4 + 5) + 2(6)] = 176.67 m². Simpson's one third rule requires an even number of equal intervals, which is satisfied by these five offsets.

About Surveying
Surveying covers measurement of distances, angles and elevations, traversing, levelling, contouring, plane table work, theodolites, total stations and basic photogrammetry. It includes error adjustment, coordinate calculations, area and volume determination, and the distinction between accuracy and precision, as well as between temporary and permanent adjustments.
