Answer:

8.11%

Step-by-step explanation:

We need to find the percentage error. We can follow the formula shown below:

$PE=\frac{New-Orig}{Orig}*100$

Where

PE is the Percentage Error

New is the newest measure (given as 20 feet)

Orig is the original, or first, measure (given as 18.5)

Substituting and finding the PE:

$PE=\frac{New-Orig}{Orig}*100\\PE=\frac{20-18.5}{18.5}*100\\PE=\frac{1.5}{18.5}*100\\PE=8.11$

Tagging the percentage , percent error is about 8.11%
