Use the distance formula three times:



where and are the coordinates of the given points.

To find the measure of each of the three sides. Then add the measures of the three sides. Leave your results in radical form if the radicands are not perfect squares if you want to represent the exact answer. Otherwise, ask your instructor for guidance as to the required precision of your answers.
