1.  A rectangular plot of land has sides 60.45±0.02 m and 50.84±0.03 m. What should be the area of the rectangular plot?
2. While measuring horizontal angles by a theodolite at station O, the following observation were recorded are A= 28⁰1’28.2”, B= 37⁰59’12.6”, C= 66⁰ 00’44.4”. Determine the most probable  values of A,B, and C
3.   The following observation were made in a rating test of a current meter with rating formula V=aN+b, where N= 0.4, 1.2, 1.6, 2.2 and V= 0.6, 1.8, 2.4, 2.5. Find the constant value a &b using least square method.
4. While measuring horizontal angles by a theodolite at station O, the following observation were recorded are A=48⁰1’28.2”, B= 76⁰59’12.6”, C= 55⁰ 00’44.4” and its wt are 3, 4, 2.  Determine the most probable values of A, B, and C.
5. using matrix method  determine the most probable of the following A= 28⁰1’28.2”, B= 37⁰59’12.6” A+2B=100⁰59’12.6” , C= 66⁰ 00’44.4”, 2B+C=140⁰59’12.6”
