It could be many shapes: for example, an ellipse with a semi major axis of length 11 and semi minor axis of length 10.
A decagon perhaps

Circumscribing.
That depends on the geometric figure.
a figure that is used in geometry
Quadrilateral is the name fr a geometric figure with 4 sides.
A geometric figure is a figure of any shape and size, and can also be flat/plane ( meaning, two dimensional like triangle, equilateral., pentagon...) or solid (3 dimensional figure like cube, pyramid, sphere..).A geometric model is a geometric figure that represents real life object like butterfly, flower, earth, etc.So a geometric kite is a two dimensional geometric figure or model.
A construction. A contruction is a geometric drawing of a figure usually made by a compass and a straightedge.
A triangle is a geometric figure that is made of three line segments. It is a closed figure and has three angles.
Drawing is creating a figure without tools (i.e. a ruler, a compass, etc.) Constructing is creating a figure with tools.
An 11-sided figure, known as a hendecagon or undecagon, is a polygon with 11 straight edges and 11 vertices. If regular, all sides and angles are equal, creating a symmetrical shape. Its appearance resembles that of a star or a complex geometric figure, depending on how it is drawn, but fundamentally, it maintains a distinct 11-sided outline.
