Answer to Question #166913 in C# for Habib

Question

Complete the project named "Shapes", adding a class named "Square" to it. For each square, we will store its starting X and Y coordinates (the upper left corner, already stored as a "Location") and the length of its side.

You will have to create:

- A suitable constructor, to assign starting values to X, Y and the side. (2 points)

- A Move method, to change X and Y coordinates. (1 point)

- A Scale method, to change its side (for example, a scale factor of 2 would turn a side of 3 into 6). (1 point)

- A method ToString, to return a string with its data (for example: "Corner (10,5), side 7". (1 point)

- Redefine "GetPerimeter" and "GetArea", so that they return the correct values (2 points).

- Another point corresponds to the attributes and the overall structure.

- The remaining 2 points correspond to the test from "Main"
