Asked by EthanTo find the area of ANY quadrilateral, you need to split it up into two triangles, work out their areas individually and add them up. Doing this with recognisable shapes like a square is where we get the formula. Area of a square is the length of one side squared, rectangle is base×height etc. If you identify the shape, it will be much easier to work out the area using the formula but if it is an irregular quadrilateral then the method above will always work.
