Question

a line segment of length 7.5cm was wrongly measured as 7.2cm what was the error percent​

Answer 1

Answer: 4%

Step-by-step explanation:

Error%= error/correct answer ×100

7.5-7.2/7.5 ×100

0.3/7.5 ×100

=100/12

=4%

Answer 2

Given:

Length of length segment = 7.5 cm

Wrongly measured length = 7.2 cm

To find:

The error percent.

Solution:

We know that the error percent of a particular quantity can be calculated by finding out the error and then dividing it by the original length and then multiplying by 100. Thus, the error percent while measuring the line segment will be:

$=\frac{7.5-7.2}{7.5} * 100\\=\frac{0.3}{7.5} * 100\\= 4%$

Thus, the error percent while measuring the line segment will be 4%.
