#d=15# units

#d=sqrt ((x_2-x_1)^2+(y_2-y_1)^2)#

Let

#(6,2)->(color(blue)(x_1),color(red)(y_1))#

#(18,11)->(color(blue)(x_2),color(red)(y_2))#

Via the distance formula:

#d=sqrt((color(blue)(18-6))^2+(color(red)(11-2))^2#

#d=sqrt((color(blue)(12))^2+(color(red)(9))^2#

#d=sqrt(144+81)#

#d=sqrt(225)#

#d=15#
