You cannot. A square can be distorted into a rhombus without changing the lengths of any of the sides, but with a different area. Similarly, the shape of any quadrilateral can be altered without affecting the length of its sides but changing its area.
Look in your math book. Square = side^2, parallelogram = base*height, etc.
well change it into another quadrilateral and then take away the area of the lines you added
Not sure what a quadrilarel is. A quadrilateral has no intrinsic sum. It has four interior angles (that sum to 360 degrees), it has four sides whose lengths can have any sum (the quadrilateral's perimeter) you want. Its area can be any number you want.
There are infinitely many possible answers. A polygon is an enclosed plane area whose boundaries comprise straight lines. The number of sides can have any value greater than 2. So apart from 4, which is a quadrilateral, you will have a name for a polygon with 3, 5, 6, 7, ... sides!
With four sides given a quadrilateral is not clear defined. Infinite are possible. You need the length of one diagonal in addition to figure out the area.

It is not possible to determine the area of a quadrilateral given only the length of its four sides.

A quadrilateral has 4 sides and 1 face which is its surface area.
To find the area of a figure with sides of different lengths, we first need to determine the shape of the figure. In this case, the sides are 5m, 3m, 4m, and 6m, which could form a quadrilateral or a triangle depending on the configuration. If it is a quadrilateral, we would need more information such as the angles between the sides to calculate the area. If it is a triangle, we could use Heron's formula to find the area. More details or a diagram would be necessary to provide an accurate calculation.

It depends on the shape of the area. Four sides of a quadrilateral - if that is what the given measurements are - do not determine a unique shape.

A "quadralateral" may be defined as a typographic error for the word "quadrilateral".
