Question

The actual length of a soccer field is 500 feet. A broken measuring instrument shows the length to be 493 feet. Find the percent error for the length of the soccer field.

Answer 1

Percent error for the length of the soccer field is 1.4 %

Explanation:

The actual length of the soccer field = 500 ft

The measured length of he field = 493 ft

ERROR in the measurement = ACTUAL LENGTH - MEASURED LENGTH

= 500 ft - 493 ft = 7 ft

So, there is an error of 7 ft in measuring the length of the field.

`\textrm{ERROR PERCENTAGE} = \frac{\textrm{Error}}{\textrm{Actual Measuement}} * 100\\= (7)/(500) * 100 = 1.4`

Hence, percent error for the length of the soccer field is 1.4 %
