    This document summarizes a student project that calculates land area bounded by irregular boundaries using the trapezoidal rule. Offsets are taken at regular intervals from a base line to the irregular boundary. The area between each pair of offsets forms a trapezoid. The program takes offset measurements as input from the user and calculates the total area by adding the individual trapezoid areas. The objectives are to determine land areas bounded by irregular boundaries in a practical way using offset measurements and calculations.

    I. Project Title
    Area by Offsets from a Straight Line: Trapezoidal rule

    II. Description
    Offsets are short distances measured perpendicular to a reference or base line. They are
    usually at a regular intervals of the curved boundary does not vary significantly.
    However, when there are abrupt changes in the boundary, it is advisable that offsets be
    taken irregular intervals. The measurement of offsets depends to a great extent on
    existing conditions of the terrain. It will be noted that when offsets are taken sufficiently
    close together the error of the measurement in area would be small as compared with the
    inaccuracies of the measured offsets.
    For this purpose from a survey line offsets are taken at regular intervals and area is
    calculated from any one of the following methods: (a) Area by Trapezoidal rule (b) Area
    by Simpson’s rule. (a) Area by Trapezoidal Rule: In trapezoidal rule, the area is divided
    into a number of trapezoids, boundaries being assumed to be straight between pairs of
    offsets. The area of each trapezoid is determined and added together to derive the whole
    area.

    The assumption made in using the trapezoidal rule is that the end of the offsets in the
    boundary line are assumed to be connected by straight, thereby forming a series of
    trapezoids . When the offsets are taken fairly close together and curves are flat, no
    considerable error is introduced by this assumption. In each trapezoid the adjacent offsets
    are taken as the bases and the common interval between offsets as the altitude.
    III. Problem Statement
    Tracts of land are not always bounded by straight lines and it is often necessary to
    determine areas that are sometimes bounded by irregular lines or curves. For instance, a
    property boundary may be represented by the centerline of a stream or it may be bounded
    by a winding road. It would not be feasible for such cases to run a traverse along the
    boundary lines. To plot the boundary it is often more practical to establish a base line
    conveniently near the irregular or curve boundary and measure offset distances from the
    base line to the boundary.

    IV. Objectives

    V. Software Functionalities
    We used the input function in order to get the user’s preferences in what would he/she
    likes to compute.
    If they choose ‘Y’, the program then asks the user for the common distance between
    offsets, the first and last offset and the intermediate offsets of each of the areas. And then
    we used the for loop so that the program will add the inputted intermediate offsets and
    get inserted to the formula. Same process for the second area as well.

    Then, when the above program is done, the first and second area will be added in order to
    get the overall area.

    If the user chooses ‘N’, only one area is going to be computed.
