Assuming "liths" is an unusual way of spelling lengths, you cannot because a quadrilateral is not a rigid shape. It can be deformed into a quadrilateral with the same sides but a different area. This can be illustrated by thinking of a square deforming into a rhombus. Same sides but different area.
It depends on the shape. There are different formulae for different shapes.
The answer will depend on the shape that the circle is embedded in! There are different formulae for different shapes.
You can name it or break it down
You would find the area of the inside and outside shape (pretending that the inside shape was not in the outside shape). then, you would take the area of the outside shape and subtract the area of the inside shape.
Shape of what ?
Fill in the blanks so that the shape makes a square and find the area of that. Then find the area of the shape you added. When you have both areas, subtract the greater from the smaller.
It all depends on what kind of surface you are trying to find the area for. Each shape has a different formula. Be more specific by saying what kind of shape you are trying to find.

Area of what? Every geometrical shape has a different formula to find its area. The simplest one: to find the area of a rectangle whose edge lengths are h and w, area = h*w.

Shape of what ?
You must know what type of geometric shape it is. However, if it is a rectangle (and you know the width), then then the formula is Area/Width=height. Edit your question if it is a different shape.
The formula will depend on the shape whose area you wish to find. There are different formulae for some simple shapes.
To find the area, first divide the shape into regular, simple shapes. Then use formulas to find the area of the smaller, regular shapes. Lastly, add up all the smaller areas to find the area of the original shape.
