Get coordinates of Translated Polygon

I have many polygons of the following form that I wish to do more complicated processing and analysis based on it’s updated location (such as relationships between geometries).

Translate[Polygon[{{0, 0}, {0, 50}, {100, 50}, {100, 0}}], {954, 840}] 

I thought I had found my solution of how to recover the coordinates of a translated Polygon from an earlier thread about Points. However, when I tried to applied Normal M12.1 just returns the expression again.

Normal[Translate[Polygon[{{0, 0}, {0, 50}, {100, 50}, {100, 0}}], {954, 840}]] 

I’ve tried some more complicated ways to extract the coordinates from a Graphics object to no avail. Does anyone have any suggestions about how they would recover the Polygons updated extents?
