Answer: The total length of nine pieces of chain is 121.248 yards.

Explanation:

Length of each chain = 13 yards, 1 foot, 5 inches

As we know that

$1\ inch=\frac{1}{12}\ foot\\\\5\ inches=\frac{5}{12}=0.4167\ foot\\\\\text{Total foot = 1+0.4167 =1.4167 foot}\\\\And\\\\1\ yard=3\ foot\\\\1\ foot=\frac{1}{3}\ yard\\\\1.4167\ foot=\frac{1.4167}{3}=0.472\ yards\\\\So,\\\\13\ yards+0.472=13.472\ yards$
