Answer: First option.
Step-by-step explanation:
You know that the meaning of the symbol of the inequality "<" is: Less than.
So, you can check each option to find the number that could be a length of this piece of wood.
Given 
, you can substitute each number given in the options into this inequality. Then:
Therefore, a lenght of the piece of wood could be 4.5
<u><em> . . five and one hundred four thousandths</em></u>
I supposed you mean similar and not congruent.
If kjn ≡ lmn, the kj would be equal to lm which in your question, is not
Assumed kjn is similar to lmn
scale = 17.5 ÷ 10 = 1.75
Therefore,
kj = 17.5 cm (given)
jn = 8 x 1.75 = 14 cm
kn = 6 x 1.75 = 10.5 cm
Perimeter = 17.5 + 14 + 10.5 = 42 cm
Answer: 42 cm
