Answer 1

Given:

Coordinates of point A are (7,3).

Point B is on the x-axis whose abscissa is 11.

To find:

The distance between A and B.

Solution:

Point B is on the x-axis whose abscissa is 11. So, x-coordinate of the point B is 11 and y-coordinate is 0. It means, coordinates of point B are (11,0).

The distance between A(7,3) and B(11,0) is

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

$D=\sqrt{(11-7)^2+(0-3)^2}$

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

$D=\sqrt{16+9}$

$D=\sqrt{25}$

$D=5$

Therefore, the distance between point A and B is 5 units.
