If a figure is reflected over the y-axis, the x-coordinate of each point is multiplied by -1.
In this case, if the length of BC in the original figure is X units, after reflection, the x-coordinate of B will be -X and the x-coordinate of C will be -2X (since C is 2 units to the right of B).
Therefore, the length of BC after reflection is 2X - X = X units.
What is the length of BC if the image undergoes a reflection over the y-axis?
BC= __ units
