Question

Find the distance between the points $R\left(-3,0\right),S\left(0,\frac{5}{2}\right)$

Answer 1

Consider the given point,$R(0,-3),S(0,\frac{5}{2})$

We know that distance between two points,

$d=\sqrt{{(x_2-x_1)}^2+{(y_2-y_1)}^2}$

$=\sqrt{{(0+3)}^2+{(\frac{5}{2}-0)}^2}$

$=\sqrt{\left(9\right)+\left(\frac{25}{4}\right)}=\frac{\sqrt{6}1}{2}$
