Task

An architect is designing a 3D model for a new building. Given the many shapes that make up a building, he wants to calculate the area of his custom shapes. For now, he wants you to create a class or constructor function called Rectangle which can both calculate the area of his walls and also tell if a wall is squarish. Because there are lots of shapes, you will also be creating a class or constructor function for all shapes named Shape. This will store properties for all shapes. Classes like Rectangle should be derived from the Shape class.
