Question

A running event map in the shape of a triangle. The triangle has sides with lengths 1.524 kilometers, 2.4 kilometers, 1.83 kilometers.
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?

The total distance is
km.

Answer 1

To find the total length of the race course, you need to sum the lengths of all three sides of the triangle. The given lengths are:

- Side 1: 1.524 kilometers
- Side 2: 2.4 kilometers
- Side 3: 1.83 kilometers

Now, let's calculate the total distance:

\[
\text{Total length} = 1.524 + 2.4 + 1.83
\]

Calculating the sum step by step:

1. \( 1.524 + 2.4 = 3.924 \) kilometers
2. \( 3.924 + 1.83 = 5.754 \) kilometers

Therefore, the total length of the race course is

\[
\text{Total distance} = 5.754 \text{ km}
\]
