Given a rectangular tract of land 690m by 1220m, the elevation at the center of the tract (E) is 165.0m and the elevation of corners A,B,C and D are 62.5m, 93.3m, 212.8m and 125.3m, respectively. Assuming uniformity of slope between the given corners, and contour interval of 20m, you are required to plot the contour lines. The contour lines with elevations of 100m and 200m to be shown as index contours.
