the perimeter
The perimeter of a plane figure is the length of its boundary. Thus the perimeter of a rectangle of length L and width W is 2L + 2W. The perimeter of a circle is the length of its circumference.
an open figure is a polygon that is not completely closed.
square
a quadrilateral.
a solid figure
its perimeter or circumference, or boundary.
the continuous line forming the boundary of a closed geometric figure
Just Measure it
Add together the length of its sides. The accumulated lengths of its sides is the perimeter.
The perimeter is the border or outer boundary around a two dimensional figure and is the length of such a boundary - a field for example, a perimeter fence
