A 20 m chain was found to be 10 cm too long after chaining a distance ...
. Find the true distance measured by the chain.

Let x be the true length of the chain and d be the true distance measured.

From the given information, we have:

x + 10 cm = 2000 m (equation 1)
x + 18 cm = d (equation 2)

Solving for x in equation 1, we get:

x = 2000 m - 10 cm
x = 1999.90 m

Substituting x in equation 2, we get:

1999.90 m + 18 cm = d
1999.90 m + 0.18 m = d
d = 2000.08 m

Therefore, the true distance measured by the chain is 2000.08 m.
