Explaination :

Here we would be using distance formula to calculate the distance between those two points.

★ Points are,

  • (3 , 9)
  • (-2 , 4)

★ Distance Formula :

  • [tex]\huge \large \boxed{\sf{{d \: = \: \sqrt{(x _{2} - x _{1}) {}^{2} \: + \: (y _{2} - y _{1}) {}^{2} }}}} \: \red\bigstar[/tex]

★ We have :

x1 = 3

x2 = -2

y1 = 9

y2 = 4

★ Substituting the values :

  • Refer the attachment.

Additional Information :

Centroid of a triangle :-

  • [tex]\boxed{ \sf{Centroid \: = \: \dfrac{x_1 \: + \: x_2 \: + \: x_3}{3} }} \: \pink\bigstar[/tex]

Midpoint of two points:-

  • [tex]\boxed{ \sf{M \: = \: \dfrac{x_1 \: + \: x_2 }{2} \: , \: \dfrac{y_1 \: + \: y_2 }{2}}} \: \pink\bigstar[/tex]
