With regard to Trigonometric Levelling, which one of the following statements is correct at its simplest applications?

The following statements are made with reference to the contour lines and contour interval. Which of the following is/are incorrect statement/s?

The following readings were taken with a tacheometer with a horizontal line of sight on a vertical staff: 0.9, 1.2, 1.62. Determine the horizontal distance between the staff station to the instrument station and the R.L of the staff station. Consider the R.L of the instrument station is 100.1 m and the height of the trunnion axis is 1.60 m. The additive constant is 0.15 m and the multiplying constant is 100 for the given tachometer.

The following perpendicular offsets are taken at 3m intervals from a traverse to an irregular boundary line: 2m, 3.15 m, 4.30 m, 3.60 m, 7.50 m, 6.45 m, 4.65 m, 3.14 m.

The area enclosed between the traverse line and the irregular boundary is calculated using Trapezoidal and Simpson's rule. Choose the correct statement/s from the following:
