Answer: 25
Step-by-step explanation:
[tex]x_{1}[/tex] = -3
[tex]x_{2}[/tex] = 21
[tex]y_{1}[/tex] = 4
[tex]y_{2}[/tex] = 11
The formula for calculating distance between two points is given as :
D = [tex]\sqrt{(x_{2}-x_{1}) ^{2}+(y_{2}-y_{1}) ^{2}}[/tex]
Substituting the values , we have
D = [tex]\sqrt{(21-[-3])^{2}+(11-4)^{2}}[/tex]
D = [tex]\sqrt{(21+3)^{2}+(11-4)^{2}}[/tex]
D = [tex]\sqrt{(24)^{2}+(7)^{2}}[/tex]
D = [tex]\sqrt{625}[/tex]
D = 25
