To help you with the reflection of a figure across the x-axis, I would need a bit more information about the specific figure you're referring to. Generally, when a shape is reflected across the x-axis, the y-coordinates of its vertices change signs, while the x-coordinates remain unchanged.
For example, if you have a rectangle with vertices at (a, b), (a, d), (c, b), and (c, d), after reflecting it across the x-axis, the vertices would become (a, -b), (a, -d), (c, -b), and (c, -d). The lengths of the sides of the figure would remain the same, as reflections do not alter distances, only positions.
If you provide the coordinates or dimensions of the original figure, I can give you a more detailed answer regarding the lengths of the sides in the reflected figure.
