Illustrative Solution for Lesson 4 Elena Walked 12 Units

Start by noting the initial position and measuring each segment of the path traveled. Each change in direction or distance is a key point to track. In this case, the total distance covered must be calculated by adding each individual movement together.

Next, verify the measurements for accuracy. Ensure that all distances are properly accounted for, even if the movement includes turns or reversals. By keeping a clear record of each change, you will avoid overlooking any segment that contributes to the total length.

Once you’ve completed the calculation, cross-check your results with the provided solution to ensure your approach aligns with the expected method. If discrepancies arise, reassess the steps to pinpoint any errors in measurement or understanding.
