Answer 2

Answer:

$2.236$ or $\sqrt{5}$

Step-by-step explanation:

Step 1 of 2:

Given two points: (0,0) and (2,1)

To find: The distance between two points.

The distance formula is;

$d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2} }$

Step 2 of 2:

Now substitute given point in the distance formula.

$(x_{1},y_{1})=(0,0)\\(x_{2},y_{2})=(2,1)$

$d=\sqrt{(2-0)^{2}+(1-0)^{2}}\\d=\sqrt{(2)^{2}+(1)^{2}}\\d=\sqrt{4+1}}\\d=\sqrt{5}}$

$d \approx 2.236$

The distance between the points (0,0) and (2, 1) is $2.236$ or $\sqrt{5}$.
