Set the translate attribute of the rectangle to the coordinate (150px, -150px) to form a door, use the position attribute to translate the horizontal and vertical axes to the specified coordinates of the parent component (square), set the scale attribute to scale up the parent and child components together to determine the window size, and use the skewX attribute to skew the component and set the coordinate translate(200px,-830px) to form a chimney.
