From the given data:

Station Occupied: A

Station Observed: B

Elevation of $A=93\mathrm{.}13m$

Height of telescope above station mark $=1\mathrm{.}75$

Rod reading at $B=1\mathrm{.}64m$

Vertical Angle $=+5\mathrm{.}4$

Stadia intercept $=0\mathrm{.}86m$

Stadia interval factor $=100$

Stadia Constant $=0\mathrm{.}30$

Compute the difference in elevation of A and $B.$ Compute the elevation of $B.$
