What is the length of the proposed PAREX?

• A. 25.0 kilometers.
• B. 12.5 kilometers.
• C. 19.37 kilometers.
• D. 31.0 kilometers.

Answer: (C)

Calculating the length of a proposed route is about adding every piece that makes up the path, while keeping all distances in the same unit and using arc length for any curved portions.

If you have several straight segments, sum their lengths after converting them to kilometers. If there’s a curved section described by a radius and an angle, use the arc length formula s = rθ (with the angle in radians). When you combine all these pieces and round appropriately, the total length given by the data matches 19.37 kilometers. This value fits the described route without altering any piece beyond what the data allows, making it the best match among the options.
