Answer: 35.80 %
Step-by-step explanation:
Given
Sophia mistakenly cut 10.2 inches
The actual cut should be 16 inches
[tex]\Rightarrow \% \text{error}=\dfrac{\text{Actual dimension-Faulty dimension}}{\text{Actual dimension}}\times 100\\\\\Rightarrow \% \text{error}=\dfrac{16-10.2}{16.2}\times 100=35.80\%[/tex]
