Answer:
The correct option is B.
Step-by-step explanation:
The distance between two points is
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
From the given figure it is clear that the coordinates of G are (1,2) and the coordinates of H are (6,5).
[tex]D=\sqrt{(6-1)^2+(5-2)^2}[/tex]
[tex]D=\sqrt{(5)^2+(3)^2}[/tex]
[tex]D=\sqrt{25+9}[/tex]
[tex]D=\sqrt{34}[/tex]
[tex]D=5.83[/tex]
[tex]D\approx 5.8[/tex]
The length of GH is 5.8 units. Therefore the correct option is B.
