Question

A student measures the width a sheet of paper and finds that the width is 22 cm. The label on the package indicates than the paper width is 21 cm. Calculate the percentage error in the masurement

Answer 1

percent error = 4.8 %

Step-by-step explanation:

Given data:

measured width = 22 cm

accepted or given value of width = 21 cm

percent error = ?

Solution:

Formula:

percent error = (measured value - accepted value/ accepted value) × 100%

Now we will put the values in equation

percent error = (22 cm - 21 cm/ 21 cm) × 100%

percent error = 0.048 × 100%

percent error = 4.8 %
