Answer 1

Percent Error = -2.8%

Explanation:

Percent error is found by the formula:

Percent error =
`(Recorded-Original)/(Original)*100`

• Recorded value is 44.25 m
• Original value is 45.5 m

Putting it in the formula, we get:

`(Recorded-Original)/(Original)*100\\=(44.25-45.5)/(45.5)*100\\=-2.75`

Rounded to nearest tenth of a percent: -2.8%
