Make area and perimeter as calculable properties, with getters

I expect something like

class Shape {
  var area: Float { get }
  var perimeter: Float { get }
}

smthng like this?

class Squere: Rectangle {

private var side: Float

init(side: Float) {

    self.side = side
    super.init(height: side, width: side)
}

var areaa: Float {
    get {
        return pow(self.side, 2)
    }
}

var perimeter: Float {
    get {
        return 4 * self.side
    }
}

}

yes and no,

• pls fix areaa
• you don't need this props at all in Square, they will be automatically calculated in its parent Rectangle
• you should change Shape protocol, add there calculable props and remove functions
• you should change Rectangle class so that it should have perimeter and area as calculable properties

I think fixed)
