A = actual length of the nail = 12 centimeters
B = measured length of the nail = 15 centimeters
percentage error formula is given as
percentage error = (measured value - actual value) x 100 /actual value
hence
percentage error = (B - A) x 100/A
inserting the above values in the formula we get
percentage error = (15 - 12) x 100/12
percentage error = 25%
hence the percentage error in roger's measurement is 25%
