$\sqrt{2.5}$ $sqrt(2.5)$

Explanation:

We have: $(4, 2.5)$ $(4, 2.5)$ and $(2.5, 3)$ $(2.5, 3)$

$\Rightarrow d = \sqrt{{(2.5 - 4)}^{2} + {(3 - 2.5)}^{2}}$ $=> d = sqrt((2.5 - 4)^(2) + (3 - 2.5)^(2))$

$\Rightarrow d = \sqrt{{(- 1.5)}^{2} + {(0.5)}^{2}}$ $=> d = sqrt((- 1.5)^(2) + (0.5)^(2))$

$\Rightarrow d = \sqrt{2.25 + 0.25}$ $=> d = sqrt(2.25 + 0.25)$

$\Rightarrow d = \sqrt{2.5}$ $=> d = sqrt(2.5)$

Answer is $d =$ $d=$ $5 \sqrt{0.1}$ $5sqrt0.1$ .

Explanation:

Distance (d) $= \sqrt{(x_{2} - x_{1}) + (y_{2} - y_{1})}$ $=sqrt((x_2-x_1)+(y_2-y_1)$ .
$:.d=sqrt((4-2.5)^2+(2.5-3)^2) =sqrt((1.5)^2+(-0.5)^2) =sqrt(2.25+0.25) =sqrt2.50 =5sqrt0.1$

$:.$ $d=$ $5sqrt0.1$ (answer).
