Final answer:
The question lacks detail and has errors that prevent providing a definite answer for the area and perimeter of the shaded region. Normally, this would require solving the involved equations and using geometry or calculus based on the shape created by the lines.
Step-by-step explanation:
The question seems to be asking for the expression of the area and perimeter of a shaded region described by certain linear equations. However, it contains typographical errors and lacks the clarity required to provide a specific answer. When given properly defined linear equations and a clear description of the shaded region, the area can be found by integrating the function over the given interval, and the perimeter involves adding the lengths of the boundaries. Typically, without a graph or more context, it's not possible to give a specific expression for either the area or the perimeter.
If the provided equations were meant to represent lines on a graph, we would need to solve them and find the coordinates of intersection which would serve as vertices for the shaded region. From there, we could calculate the area using geometrical formulas or calculus, depending on the shape that's formed. Similarly, by finding the lengths of the sides of the shaded region, we could sum them up to find the perimeter.
