- The following tabulation (see image) gives elevations of points over the area of a 60-by-100 ft city lot. The elevations were obtained by the checkerboard method, using 20-ft squares. Point A-1 is in the northwest corner of the lot, and point F-1 is at the southwest corner. Plot the contours, using preferred scale and a contour interval at 2 feet.Q3)The figure below represents a grid for a parcel with (25 m x 25 m) sub-grid dimensions Draw the contour line with elevation=41.00 m using a horizontal seale =1/500. 33.14 m 43.24 m 32.22 m 35.74 mGiven data of area with irregular boundary, complete the table and determine the area by trapezoidal method.
