A piece of steel rebar is tested in tension to determine its mechanical properties. The length of the sample is 87.3 mm and the cross-sectional area is 52.1 mm². When stretched by 37.2 mm, the force measured is 14,884 N. At this point, the graph is non-linear, but no clear neck is visible. If the Poisson's ratio of the material is 0.281, calculate the cross-sectional area (mm²) at this point.
