Step-by-step explanation:
coordinate point of B(2,5)
and coordinate point ofC(3,1)
Distance of BC
[tex] \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } [/tex]
[tex] = \sqrt{ {(3 - 2)}^{2} + {(1 - 5)}^{2} } [/tex]
[tex] = \sqrt{ {1}^{2} + {( - 4)}^{2} } [/tex]
[tex] = \sqrt{1 + 16} = \sqrt{17} = 4.12 = 4.1[/tex]
