The term "length of a quadrilateral" is somewhat ambiguous, as quadrilaterals have sides of varying lengths. Instead, one typically refers to the perimeter, which is the total distance around the shape, calculated by adding the lengths of all four sides. If you have the specific lengths of each side, you can find the perimeter using the formula: Perimeter = side1 + side2 + side3 + side4.
The area of the quadrilateral.

It depends on what kind of quadrilateral is. Still, you can't solve it.

The area of the quadrilateral.
A Quadrilateral has two diagonals. IF the quadrilateral is a rectangle, then the two diagonals are equal in length.
Nope - a quadrilateral is defined as having four sides of equal length.
Yes, be it a common convex quadrilateral or a concave quadrilateral. For a convex quadrilateral, the most obvious example is a irregular trapezium, where the upper base and the lower base are of different length, and the slanted sides are of different length. It is similar for a concave quadrilateral.
Area
One.
rhombus
Area divided by length= width

No, a quadrilateral must have 4 sides. If it is a proper quadrilateral it must have 4 sides of equal length but if it is an irregular quadrilateral it must have 4 sides but not have equal sides. An example of a quadrilateral could be a square. A pentagon on the other side must have 5 sides.
