From the constructed contour map, it can be determined that the elevation of point R is somewhere between (choose letter of the answer) a. 160m and 180m b. 180m and 200m c. 140m and 160m d. 120m and 140m e. 100m and 120m

Extracted text: sketch). The elevation at the center of the tract (E) is 165.0 m and 13. Giyen a rectangular tract of land 690 m by. 1220 m (ee accompenying the elevation of corners A, B, C, and D are 62.5 m, 93.3 m, 212.8 m, and 125.s m, respectively. Assuming uniformity of slope between the given corners, and contour interval of 20 m, you are required to plot the contour lines. The contour lines with elevations of 100m and 200m are to be shown as index contours. to to 1220 m NOTE: Trace accurately the given sketch on a separate shoet of paper. Do not plot on the quationaire. 690 m
