Question

Karen measured her height as 147 cm. Karen’s actual height is 142 cm. What is the approximate percent error of Karen’s measurement?

Answer 1

The actual height of Karen = 142 cm

The measured height of Karen = 147 cm

We have to determine the approximate percent error of Karen's measurement.

The difference in the heights = 147 cm - 142 cm = 5 cm

So, Error percentage =
`(5)/(142) * 100`

=
`(500)/(142)`

= 3.52

= 3.5 (approximately)

So, the approximate percent error of Karen's measurement = 3.5%
