Question

9th Grade Geometry Describe and correct the error in finding the length of line segment AB

Answer 1

The correct option regarding the error in calculating the length of segment AB is given as follows:

There should have been a subtraction instead of an addition, and the correct length is of 3.5 units.

Where are points A and B?

Researching the problem on the internet, it is found that points A and B are on a number line, with coordinates given as follows:

• A: 1.

• B: 4.5.

What is the length of the segment?

The length of the segment is the absolute value of the subtraction of the endpoints, hence:

L = |4.5 - 1| = |1 - 4.5| = 3.5.

The error is that:

There should have been a subtraction instead of an addition, and the correct length is of 3.5 units.
