Perspective, perhaps.
trompe l'oeil
In math, area is defined as the amount of space a geometrical object takes up on a two-dimensional plane. It is the measure of the surface of an object.
You need to find the area of each two dimensional surface on the figure. Do you have a specific figure in mind?
A face.

Visual texture.
Trompe L'oeil, maybe, though it's not really related to the Math, Algebra, Geometry category.
The term for the creation of the illusion of three-dimensional texture on a two dimensional surface is "visual texture." There are many ways of achieving visual texture, including relief, shading, and perspective.

It is called perspective.
Linear perspective is the term defined as the use of horizontal and diagonal lines to create the illusion of depth in a two-dimensional artwork. By converging lines to a vanishing point on the horizon, artists can achieve a sense of space and distance on a flat surface.
