Astudent buys a rope at the store. the label on the packaging says that he rope is 2.15 meters in length. the student measures the rope at 1.85cm. what is the student's percent error?

percent error =  - 99.134 %

Explanation:

Given data:

measured length = 1.85 cm

accepted or given value length = 2.15 m

percent error = ?

Solution:

First of all we will convert the length in meter into cm.

1 meter = 100 cm

2.15 × 100 = 215 cm

Formula:

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

Now we will put the values in equation

percent error = (1.85 cm - 215 cm/ 215 cm) × 100%

percent error = -0.9914 × 100%

percent error =  - 99.134 %
