What is the length of the segment connecting the points A(1,3) and B(6,5)?

Natalija [7]

Answer:

The answer is

<h2> $\sqrt{29} \: \: \: or \: \: \:5.38 \: \: \: units$ </h2>

Step-by-step explanation:

The length of the segment connecting two points can be found by using the formula

$d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A(1,3) and B(6,5)

The length is

$|AB| = \sqrt{ ({1 - 6})^{2} + ({3 - 5})^{2} } \\ = \sqrt{ ({ - 5})^{2} + ( { - 2})^{2} } \\ = \sqrt{25 + 4} \\ = \sqrt{29}$

We have the final answer as

$\sqrt{29} \: \: \: or \: \: \:5.38 \: \: \: units$

Hope this helps you
