A quadrilateral is a four sided figure, so sum the lengths of its four sides.
a trapezoid.
For a general quadrilateral, the only way is to divide it into two triangles, calculate the area of each and add the two answers together.To do this, you will require 5 pieces of information. These could be the lengths of the four sides and a diagonal, or four sides and any angle (other variations are possible).Formulae involving "height" for example, assume that the quadrilateral has at least one pair of parallel sides. The quadrilateral need not have any parallel sides!
It is not possible to answer the question. The fact that there are four lengths given suggests that the shape is quadrilateral. However, for a quadrilateral, the side lengths do not provide enough information since a quadrilateral can be skewed: from a trapezium to a narrow needle-like shape.
The only thing that can be said about consecutive sides of a quadrilateral is that they meet at a vertex. There is no restriction on the angle, nor on their respective lengths.
You don't. There is no such thing as the "sum of a quadrilateral". If you mean the perimeter, you add the lengths of the four sides. If you want the area, you can divide the quadrilateral into two triangles, or some other shapes, calculate the individual pieces, and add everything up.
What are the lengths of the sides of a quadrilateral if the perimeters is 54 inches
All quadrilaterals have 4 sides of various lengths and the 4 sides added together is the perimeter
Any polygon with 4 sides is a quadrilateral
rhombus
The perimeter of a quadrilateral is always equal to the sum the lengths of its four sides. So perimeter = Side1 +Side2 + Side3 +Side4. If the quadrilateral happens to be a parallelogram, a quick way to calculate the perimeter is 2 x length of base + 2 x length of height.

When it has 4 sides of the same lengths
A regular polygon has all sides equal in lengths. A quadrilateral is a 4 sided polygon.

How about a rectangle which is a quadrilateral with sides of different lengths
