Summary We show that the area under a catenary curve is proportional to its length in the following sense: given a catenary curve, we can take any horizontal interval and examine the ratio of the area under the curve to the length of the curve on that interval, and we find that the resulting ratio is independent of the chosen interval. This property extends to the three-dimensional case as well: the volume contained by a horizontal interval of a catenoid surface is proportional to its surface…

This work considers the rectangular domain of positive C^1 functions defined on the n-dimensional Euclidean space with nonzero numbers with coefficients x=(x_1,\cdots, x_n), where \$I(x_i)= [0, x-i]\$ if \$x-i>0 and \$I-i= [x- i,0] if \$ x- i>0.

Two higher-dimensional generalizations of this invariant ratio of the catenary curve are developed and it is found that each invariant ratios identifies a class of hypersurfaces connected to classical objects from differential geometry.
