Question

Find the distance between the point $P(2,3)$ and $x-$axis.

Answer 1

The distance between point $(2,3)$ & x-axis can be determined by assuming a point $(2,0)$ in x-axis.

Now distance between A & B is $P=\sqrt{(x_2-x_1{)}^2+(y_2-y_1{)}^2}$

$P=\sqrt{(2-2{)}^2+(3-0{)}^2}$

$[P=3$ unit$]$

Hence distance between point A & x-axis is $3$ unit.
