Answer 1

For different resize corner

$('.rect-item').resizable({
        handles: 'n,e,s,w,ne,se,sw,nw',
        resize: (e, ui) => {
          const zoomScale = Your scale;
          const changeWidth = ui.size.width - ui.originalSize.width; // find change in width
          const newWidth = ui.originalSize.width + changeWidth / zoomScale; // adjust new width by our zoomScale

          const changeHeight = ui.size.height - ui.originalSize.height; // find change in height
          const newHeight = ui.originalSize.height + changeHeight / zoomScale; // adjust new height by our zoomScale

          ui.size.width = newWidth;
          ui.size.height = newHeight;

          // here
          const posOrigin = ui.originalPosition;
          if (posOrigin.left !== ui.position.left) {
            ui.position.left = posOrigin.left - changeWidth / zoomScale;
          }
          if (posOrigin.top !== ui.position.top) {
            ui.position.top = posOrigin.top - changeHeight / zoomScale;
          }

        }
      });
