Question

Find the distance between the following pair of points.
$(2,3)$ and $(4,1)$.

• A. $2\sqrt{2}$
• B. $2\sqrt{3}$
• C. $2\sqrt{5}$
• D. $2\sqrt{7}$

Answer 1

The correct option is A $2\sqrt{2}$

Distance formula: The distance between points $(x_1,y_1)$ and $(x_2,y_2)$ is given by $\sqrt{{(x_2-x_1)}^2+{(y_2-y_1)}^2}$

$\therefore$ Required distance $=\sqrt{(2-4{)}^2+(3-1{)}^2}$

$=2\sqrt{2}$
