Question

The length of a line measured with a 20 m chain was found to be 250 m. Calculate the true length of
the line if the chain was 10 cm too long.
a) 252.25 m
b) 251.25 m
c) 225.25 m
d) 221.25 m​

Answer 1

Answer:

length of the chain is 20 + 10/100, ie 20.1 m. Measured length is 250,

hence true length of the line is 250 × (20.1/20)=251.25 m.
