Total length of string = 30'

According to the figure,

$\quad \twoheadrightarrow\sf { 30' = 15' + A + 9' } \\$

$\quad \twoheadrightarrow\sf { 30' = 24' + A} \\$

$\quad \twoheadrightarrow\sf { 30' - 24' = A} \\$

$\quad \twoheadrightarrow\underline{\boxed{\sf { 6' = A}}} \\$

Therefore, the missing dimension in the dimension strings is 6'.
