. A stadia survey was conducted to determine the width of a river using a surveyinstrument with an internal focusing telescope. The instrument was set up on the leftbank of the river and took rod readings on the left and right water edges. The stadiainterval factor is 100, and the stadia constant is zero.

I need Answer of A only A. A tachometric surveying was conducted to obtain some readings forinaccessible points, where it was found that the multiplying and additiveconstants are 98 and 0.1, respectively. The instrument was setup at point C and the readings listed in the table were taken while the staff was held vertically. Calculate the horizontal distance between BM and station D. Also, calculate the reduced level of station D. Figure 1 shows a schematic view of the site.
