How to get an actuate diminsion of filleted plane

Hello, imagine that I have a rectangular block with an edge being filleted. I want to design a thin sheet such as a label to put on top of the surface that has the filleted edge. If I print the sheet based on a 2D top view of the rectangular block, the size of the printed sheet will not be able to cover this surface because the 2D view does not take the cured surface into account. Is there a way to get an accurate dimension of the surface that contains the filleted edge/surface?
