The red lines on the diagram show the layout for a running event. Runners will race around the triangle-shaped grassy area. What is the total length of the race course? what is The total distance in km.

Total distance = 5.754 km

Step-by-step explanation:

Red lines of the right triangle show the layout of the race course.

Total length of the race course = Perimeter of the triangle

Perimeter of the triangle = Sum of the measures of all three sides

                                         = 1.83 + 1.524 + 2.4

                                         = 5.754 km

Therefore, total distance of the race course is 5.754 km.
