$d = 5$ $d = 5$ units

Explanation:

Distance = $\sqrt{{(x_{2} - x_{1})}_{2}^{2} + {(y_{2} - y_{1})}_{2}^{2}}$ $sqrt((x_2-x_1)^2 + (y_2-y_1)^2$
Here, $x_{2}$ $x_2$ is 10,
$x_{1}$ $x_1$ is 7,
$y_{2}$ $y_2$ is 8,
$y_{1}$ $y_1$ is 4.

Substituting and solving we get:
$d = \sqrt{{(10 - 7)}^{2} + {(8 - 4)}^{2}}$ $d = sqrt((10-7)^2 + (8-4)^2$
$d = \sqrt{3^{2} + 4^{2}}$ $d = sqrt(3^2 + 4^2)$
$d = \sqrt{9 + 16}$ $d = sqrt(9+ 16)$
$d = \sqrt{25}$ $d = sqrt(25)$
$d = 5$ $d = 5$ units
