(b) Explain the principles of surveying?                                                     (3)

(c) The Length of a survey line was measured with 20 m chain and was found to be equal          to 1200mm. As a check the length was again measured with a 25 m chain and was              found to be 1212m. on Comparing the 20 m chain with the test gauge, it was found            to be 1 decimeter too long. Find the actual length of the 25 m chain used?           (3)
