We have to use the distance formula.

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

(13, 20), (18, 8)
x1 y1 x2 y2

Plug in what we know:

$\sf~d=\sqrt{(18-13)^2+(8-20)^2}$

Subtract:

$\sf~d=\sqrt{(5)^2+(-12)^2}$

Simplify exponents:

$\sf~d=\sqrt{25+144}$

Add:

$\sf~d=\sqrt{169}$

Find the square root:

$\sf~d=\boxed{\sf13}$
