If the contour interval and contour gradient of a contour map plotted over an undulated terrain are 10m and 1 in 100, then the horizontal equivalent is :

Statement (I): A series of closed contour lines on the map indicates a valley, if the higher values are outside.

Statement (II): When contour lines are close together, it indicates a flat ground.

Planimeter is an instrument used to measure

Consider the following statements regarding Simpson’s rule

(i) It is an approximate method of analysis.

(ii) It assumes boundary line between offsets to be parabola.

(iii) To apply Simpson’s rule odd number of sections are required.

Which of the above statements are correct?

To determine area of a narrow tract of land offsets are taken at regular interval from the base line and average of all ordinate is multiplied by the length of base line. This method of computation of area is called

Statement 1: Simpson’s rule for area measurement is more accurate than Trapezoidal Method.

Statement 2: Computations involved in Simpson’s rule are more complex as those in trapezoidal rule.

Volume of an embankment having depth 50 m is to be calculated using End Area method. For this, area at top, bottom and middle of embankment is found to be 32 m², 84 m² and 68 m² respectively.

Volume of embankment is
