R[R + sp package], 55 bytes

function(x)round(sp::Polygon(x[chull(x),,drop=F])@area)

Try it at RDRR

A function which takes a n x 2 matrix and returns the rounded area. This uses the sp package. The drop=F is needed to handle the one co-ordinate case. RDRR used for demo since TIO lacks the sp package.
