Use the image to answer the question.

A coordinate grid shows the x-axis ranging from negative 12 to 12 and the y-axis also ranging from negative 12 to 12. Points labeled with winter activities are plotted. Sledding is plotted at left parenthesis 2 comma 12 right parenthesis. Skiing is plotted at left parenthesis negative 8 comma negative 4 right parenthesis, and ice skating is plotted at left parenthesis 2 comma negative 4 right parenthesis.

Shahriyar is at a winter park with his family. They go sledding first, then ice skating, then skiing. What is the total distance traveled between these locations?

To find the total distance traveled, we need to find the distance between each pair of points and then add them together.

The distance formula is given by:
$$
d = \sqrt{{(x2 - x1)^2 + (y2 - y1)^2}}
$$

Using this formula, we can calculate the distance between the points.

Distance between sledding and ice skating:
$$
d_1 = \sqrt{{(2 - 2)^2 + (12 - (-4))^2}} = \sqrt{{(0)^2 + (16)^2}} = \sqrt{{256}} = 16
$$

Distance between ice skating and skiing:
$$
d_2 = \sqrt{{(2 - (-8))^2 + (-4 - (-4))^2}} = \sqrt{{(10)^2 + (0)^2}} = \sqrt{{100}} = 10
$$

Total distance traveled:
$$
d_{total} = d_1 + d_2 = 16 + 10 = 26
$$

Therefore, the total distance traveled between the three locations is 26 units.
