a ruler
The answer is Area. The answer is Area.
The measure of the amount of surface enclosed by the boundary of a figure is called its area. Area quantifies the two-dimensional space within the perimeter of a shape, such as a rectangle, circle, or triangle. It is typically expressed in square units, such as square meters or square feet.
Another term for a geometric figure that is enclosed by a circle is a "circular region" or "disk." This refers to the area contained within the circumference of the circle. In a broader context, you might also refer to it as a "circle" itself when discussing its boundary.
That's the 'volume' of the figure.

isn't it called face?
-- The amount of paper you'd have if you cut the figure out. -- The amount of carpet you need to completely cover the figure.
If it's a 3 dimensional shape then it is volume otherwise it is surface area
