Question:
Which rule is used for computing area from offsets?
Which rule is used for computing area from offsets?
Show Hint
The trapezoidal rule is commonly used in surveying for calculating areas from offsets.
Updated On: May 7, 2026
- The Mid-ordinate rule
- The Average ordinate rule
- Simpson's rule
- The Trapezoidal rule
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
In surveying, irregular areas can be calculated from offsets taken at regular intervals.
Step 1: When offsets are measured from a baseline, the boundary may not be a straight line.
Step 2: The area can be divided into small trapezoids.
Step 3: The trapezoidal rule is used to compute the approximate area from these offsets.
Step 4: Therefore, the required rule is: \[ \boxed{\text{The Trapezoidal rule}} \]
