Answer 1

Try some thing like below (Not tested, but will give you an idea).

create some objectname for rectangle as shown below:

Rectangle {
        id: rectangle
        x: 187
        y: 92
        width: 200
        height: 200
        color: "blue"
        objectName: "myRect"
    }

Interact with QML and find your child, then set the property.

    #INTERACT WITH QML
    engine = QQmlEngine()
    component = QQmlComponent(engine)
    component.loadUrl(QUrl('mainViewofHoomanApp.qml'))
    object = component.create()

    #FIND YOUR RECTANGLE AND SET WIDTH
    child = object.findChild(QObject,"myRect")
    child.setProperty("width", 500)
