Questions: The standard length of a football field is 4,320 inches long. You measure your local football field and it measures at 4,225 inches. What is the percent error? % Error = (accepted -average / accepted) x 100

Solution Steps

The accepted length of the football field is 4,320 inches, and the measured length is 4,225 inches.

Calculate the absolute difference between the accepted and measured values: $$|\text{accepted} - \text{measured}| = |4320 - 4225| = 95$$

Use the percent error formula: $$\% \text{ Error} = \frac{|\text{accepted} - \text{measured}|}{\text{accepted}} \times 100$$ Substitute the values: $$\% \text{ Error} = \frac{95}{4320} \times 100 \approx 2.1991$$
