    (a) Mid ordinate rule (b) Average ordinate rule (c) Trapezoidal rule (d) Simpson’s
    rule.

Find the area enclosed between the boundary, chain line and the end offsets.

6. (a) Explain the principle of chain and compass surveying.
    (b) Explain briefly about the theodolite surveying and briefly explain its essential
          parts.

7. Explain briefly about the level and leveling staff, with suitable sketches.
8. The following staff readings were taken with a level, the instrument having been
    moved after third and seventh readings:
    2.340; 1.725; 0.625; 2.890; 2.200; 1.420; 0.805; 0.505; 1.485; 0.980
