Question

Determine the distance between (2,1) and (12,13)

Answer 1

Answer:

$d = 15.620499$

Step-by-step explanation:

To solve this question, we must use the following distance equation:

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

Plug your coordinates into the equation. Remember, a coordinate is denoted as (x, y).

$\sqrt{(12-2)^{2} + (13-1)^{2}}$

$\sqrt{(10)^{2} + (12)^{2}}$

$\sqrt{100+144}$

$\sqrt{244} = 15.620499$
