You could use the distance formula, but another way is the Pythagorean theorem.

3² + 5² = c²
9 + 25 = c²
34 = c²
c = 5.83
Rounded = c = 6

The approximated length of GH is 5.83

How to determine the length GH?

From the graph, we have the following points

G = (1,2)

H = (6.5)

The distance is then calculated using:

GH^2 = (x2 - x1)^2 + (y2 - y1)^2

Substitute known values:

GH^2 = (6 - 1)^2 + (5 - 2)^2

Evaluate the sum

GH^2 = 34

Take the square root of both sides

GH = 5.83

Hence, the length of GH is 5.83
