Answer:

[tex]\sqrt{85}[/tex]

Step-by-step explanation:

we have the equation of distance between two points :

d=[tex]\sqrt{(x2-x1)^2+(y2-y1)^2}[/tex]

first point (21,5)

second point (28,-1)

so we have

d=[tex]\sqrt{(28-21)^2+(-1-5)^2}[/tex]

d=[tex]\sqrt{(7)^2+(-6)^2}[/tex]

d=[tex]\sqrt{49+36}[/tex]

d=[tex]\sqrt{85}[/tex]

so we have

d=[tex]\sqrt{85}[/tex]
