i used syncfusion pdfviewer to draw the rectangle. i asked them how to get the rectangle coordinates but they emailed me that the control doesn't have a functionality right now for that.

Is this question related to stackoverflow.com/questions/40126232/… and if yes, how exactly? It looks like you are asking several questions about one project you're working on. It's good that you split it up in several pieces, but it might be helpful if you gave a bit of background information. – Amedee Van Gasse
Your rectangles are added to the document as Square annotations. Thus, you merely have to inspect the annotations of the page, retrieve these annotations, and get the coordinates from the annotation objects. – mkl

We can get the rectangle coordinates by retrieving the annotations of the PDF page as PdfLoadedAnnotationCollection.   

Please find the code snippet to achieve the same. 

PdfLoadedDocument pdf = new PdfLoadedDocument(@"../../Data/3333.pdf");     
PdfLoadedPage lpage = pdf.Pages[0] as PdfLoadedPage;     
PdfLoadedAnnotationCollection collection = lpage.Annotations;     
for (int i = 0; i < collection.Count; i++)     
{     
    PdfLoadedRectangleAnnotation rectAnnot = collection[i] as PdfLoadedRectangleAnnotation;     
    RectangleF bounds = rectAnnot.Bounds;     
} 

As per your requirement, we have created a sample to get the rectangle coordinates by using the above snippet. Please find the sample from the below link,
