The distance between these two points is 61 units.

The formula for calculating the distance between two points is:

$d = \sqrt{{(x_{2} - x_{1})}_{2}^{2} + {(y_{2} - y_{1})}_{2}^{2}}$ $d = sqrt((x_2 - x_1)^2 + (y_2 - y_1)^2)$

Substituting the values given in this problem gives us:

$d = \sqrt{{(80 - 20)}^{2} + {(55 - 44)}^{2}}$ $d = sqrt((80 - 20)^2 + (55 - 44)^2)$

$d = \sqrt{{(60)}^{2} + {(11)}^{2}}$ $d = sqrt((60)^2 + (11)^2)$

$d = \sqrt{(3600) + (121)}$ $d = sqrt((3600) + (121))$

$d = \sqrt{3721}$ $d = sqrt(3721)$

#d = 61
