Answer:
If it helps mark me as brainliest.
Explanation:
When we assumed that the chain was 20 m long, the length of the line measured was
= 536 m
= (20×26)+16
So, the chain was fully measured 26 times.
Since the chain was 0.05 m too long, (20×0.05)= 1m was the extra length measured.
So, true length of the line= 536- 1 = 535 m.
