Question

21. Find the missing dimension in the dimension
strings below.

Answer 1

Required Answer :

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'.
