Question

((19.) A line segment joins the points P(-4,1) and’Q(1, -11). What is the length of PQ?
​

Answer 1

Answer:

The length of PQ line segment is 13units.

Step-by-step explanation:

Can be found by using distance formula

Answer 2

Answer:

Given :

Coordinates of Points are P(-4,1) and Q(1,-11).

To find :

The length of PQ =?

Formula used :

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

Solution :

$PQ \: = \sqrt{ {(1 + 4)}^{2} + {( - 11 - 1)}^{2} }$

$PQ \: = \sqrt{ {( - 5)}^{2} + {( 12)}^{2} }$

$PQ \: = \sqrt{25 + 144} = \sqrt{169}$

$PQ \: = 13cm$

Therefore the length of PQ is 13cm.
