The error was that; Pablo set up an incorrect proportion
Here, we want to get the error made by Pablo
Mathematically, when two shapes are similar, the ratio of their corresponding sides are equal
Thus, we have it that;
[tex]\begin{gathered} \frac{x}{3}=\text{ }\frac{8}{12} \\ \\ 12\times\text{ x = 8}\times3 \\ 12x\text{ = 24} \\ x\text{ = }\frac{24}{12} \\ x\text{ =2} \end{gathered}[/tex]
So, what we can see here is that he set up the wrong proportion
