3. A dumpy level with an internal focusing telescope was set up on the left bank of the river and the rod readings tabulated below were taken on a stadia rod held SUccessively at the left and right water edges. If the stadia interval factor is 100, determine the width of the river. HAIR READINGS UPPER MIDDLE LOWER ROD held at LWE 2.189 2.172 2.156 ROD held at RWE 2.277 2.173 2.069

Plugging when performing the longitudinal section leveling of a road, the readings were recorded according to the figure below. Note that the real level of the first leveling marker (BMI) is 70.00 meters and the second leveling figure (BM2) is 67.85 meters. Complete the table and verify the correctness of the calculations and the correctness of work (with adjusting the levels ().

SURVEYING. Solve the following and make a clear and full solution

Starting from point A of reduced level 200, the levels were taken to another point B. The reduced level of point B was found to be 198.295. In order to check the leveling work flying levels were taken from point B to point A and the following readings were obtained.
