Question:medium

The length of a survey line when measured with a chain of $20$ m nominal length was found to be $85$ m. If the chain used is $0.1$ m too long, the correct length of the line is

Show Hint

If the chain is
• Too long $\rightarrow$ Actual distance is greater than measured distance.
• Too short $\rightarrow$ Actual distance is smaller than measured distance. Use \[ \boxed{ L_c=L_m\left(\frac{l_a}{l_n}\right) } \]
