Question

find the length of $overline{ab}$. a 13 b 34 ab =? ab = |a - b| = |b - a| enter the number that belongs in the green box.

Explanation:

Step1: Identify the formula

The length of a line - segment with endpoints \(A\) and \(B\) is given by \(AB=\vert B - A\vert\).

Step2: Substitute the values

Here, \(A = 13\) and \(B = 34\). So \(AB=\vert34 - 13\vert\).

Step3: Calculate the result

\(\vert34 - 13\vert=\vert21\vert = 21\).

Answer:

21
