Question

While measuring a line segment of length 5 cm, it was measured 5.2 cm by mistake. Find the percentage error in measuring the line segment.

Answer 1

Answer:

4 %

Step-by-step explanation:

Original measure = 5 m

Errored measurement = 5.2 m

Thus, net error = 5.2 - 5 = 0.2 m

Thus, percentage error:

( Net error / Original measure ) × 100

= ( 0.2 / 5 ) × 100

= 0.04 × 100

= 4 %

Answer 2

The percentage error in measuring the line segment is 4%

Step-by-step explanation:

Length of line segment = 5 cm

It was measured by mistake = 5.2 cm

Error = 5.2 cm - 5 cm = 0.2 cm

Error percentage =$\frac{0.2}{5} \times 100$

Error percentage = $4\%$

Hence The percentage error in measuring the line segment is 4%
