A quadrilateral
The only classification I could give this figure would be that it is a trapezoid, perhaps.
A regular polygon has all sides equal in lengths. A quadrilateral is a 4 sided polygon.
this isn't possible, as having all sides be different lengths would prevent the sides from being parallel.
A trapezoid in the UK is a trapezium which is a 4 sided quadrilateral with 1 pair of opposite parallel sides of different lengths.
A quadrilateral
It is a trapezoid or a trapezium
All quadrilaterals have 4 sides of various lengths and the 4 sides added together is the perimeter
There is no special name. And some quadrilaterals with special characteristics (eg a trapezium) could still have all sides of different lengths.
A square has all 4 sides equal in length. A four sided closed figure with all sides different length is called a quadrilateral.
No because a rhombus is a 4 sided quadrilateral

No, because a quadrilateral can be many different sizes and lengths as a quadrilateral is any shape with only 4 sides. The sum of all the angles in a quadrilateral equal 360 degrees.
No. Take a pencil and a sheet of paper. You shouldn't have any trouble drawing something with 4 sides that are all different lengths.
