Answer:
21.1cm or 10.1cm
Explanation:
Since the percent error is 35.5% and the experimental measurement was 15.6cm, the two possible values for the actual measurement are 15.6 plus 35.5% of 15.6 or 15.6 minus 35.5% of 15.6.
This is this:
15.6 + (0.355 x 15.6)
= 15.6 + 5.54
= 21.1cm
Or this:
15.6 - (0.355 x 15.6)
= 15.6 - 5.54
= 10.1cm
