There is no such thing as an "irregular rectangle". To calculate the area of a rectangle - if that's what you mean - you multiply length x width.
For example, you can divide the polygon into triangles, and calculate the area of each triangle.
By integration, which basically means dividing the object into small pieces.
The most direct way to calculate the area of an irregular shape is to superimpose it on graph paper, and then count the number of complete squares that it covers, and for squares that are only partially covered, estimate how much of the square is covered to the nearest simple fraction (a half, a third etc.). If you want the surrounding area rather than the area of the shape itself, you could calculate the total area and then subtract the area of the shape.
Partition (or divide) the irregular object into summation of regular objects and then calculate the volume.
To calculate the area of land with different dimensions (e.g. irregular shape), you can divide the land into basic geometric shapes like rectangles, triangles, and circles. Calculate the area of each shape separately using their respective formulas, then sum up these areas to get the total land area. If the land shape is complex, you can use mapping or surveying tools to accurately measure each section and then calculate the total area.

Finding the area of an irregular shape is now quite easily done after watching the instructional video at [See related link below for the website] and it's for free
By integration. In general, if you have an irregular area, divide it into many small shapes, for example rectangles, which you know how to calculate.
The simplest way is to divide the pentagon into three triangles, calculate the area of each of them and sum the answers.

It depends on the shape of the area you need to calculate. There are formulae for given shapes but not necessarily for irregular ones
Area= width x length Alternatively, area of irregular or regular polygons can be calculated using SketchAndCalc (see related links below). A free Area and Perimeter Calculator that calculates the area of any shape you draw, regardless of scale or complexity.
To calculate the area of an irregular pentagon, you can divide it into shapes with known formulas (such as triangles and rectangles) and then sum their areas. Alternatively, you can use a formula specifically designed for irregular pentagons, such as Heron's formula if you know all the side lengths. You may also use trigonometry to calculate the area if you know certain angles and side lengths within the pentagon.
For instance, you might divide the polygons into triangles, calculate the area of each triangle, and then add everything up.
