Find the distance between the point $P(3,4)$ and the Origin.

By the distance formula :

$D=\sqrt{(x-x_1{)}^2+(y-y_1{)}^2}$

Where, $(x,y)$ and $(x_1,y_1)$ are $P(3,4)$ and origin $(0,0)$ respectively.

Now,

$D=\sqrt{(3-0{)}^2+(4-0{)}^2}=\sqrt{25}$

$D=5$

$\therefore$ Distance between given two points is 5
