2. For a proposed new road, the cross sectional areas at different sections are as follows: Station 1+000 1+020 1+040 1+060 1+080 1+100 1+120 29.6 38.4 37.6 25.5 15.0 9.7 Area(sqm) 18.4 Calculate the volume enclosed between station 1+000 and 1+120 by prismoidal and end area formula.

2. Determine the enclosed area of Lot 5, shown in the figure below. Also, compute the length of the curving boundary line BC. The data for the curved boundary line BC are given: the central angle A = 41.4° and the curve radius R = 200 ft. D N S45°E 100.00 ft A S45°W 100.00 ft Lot 5 Arc N45°E 200.00 ft Chord 141.42 ft R= 200.00 ft B A = 41.4°

Compute by DMDs the area in hectares within a closed-polygon traverse ABCDEFA by placing the X and Y axes through the most southerly and most westerly stations, respectively. Departures and latitudes (in meters) follow.AB: E dep. = 30, N lat. = 40; BC: E dep. = 70, N lat. = 10; CD: E dep. = 30, S lat. = 50; DE: W dep. = 60, S lat. = 40; EF: W dep. = 90, S lat. = 30; FA: E dep. = 20, N lat. = 70

W Calculate the end area of the given cross section (using sum of areas method). Use a base line of 260.000m. Keep calculations to 2 decimal points, show final answer to one decimal point.
