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 [tex]w<5[/tex], you can substitute each number given in the options into this inequality. Then:
[tex]1)\ w<5\\\\4.5<5\ (This\ is\ true)[/tex]
[tex]2)\ w<5\\\\6<5 (This\ is\ not\ true)[/tex]
[tex]3)\ w<5\\\\11.3<5\ (This\ is\ not\ true)[/tex]
[tex]4)\ w<5\\\\13<5\ (This\ is\ not\ true)[/tex]
Therefore, a lenght of the piece of wood could be 4.5
