To find the area of irregular shapes, first, we need to divide the irregular shape into regular shapes that you can recognize such as triangles, rectangles, circles, squares and so forth. Then, find the area of these individual shapes and add them to get an area of irregular shap

Irregular shapes are all around. Most shapes are irregular.
A Planimeter.
The best way would be to break the irregular shape down into several familiar shapes. If you can break down a complex figure into a rectangle and two triangles, for instance, you can use the known formulas for the area of those shapes to determine the total area when all added together.
I assume you mean the calculation required. Split the irregular shape up into shapes for which you can find the area (eg rectangles, triangles), then the area of the shape is the sum of the areas of the smaller shapes.
For any irregular shape, you must divide it into shapes that are regular and find the area of those then add up all of the parts to find the area of the whole.
Irregular 3-dimensional shapes.
You can find the area when you look at the angles and measure it to see if they are all the same size.
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.
You break it up into smaller shapes which are less irregular. If these are more regular, you can calculate their contribution to the perimeter, and their area. You can then add these together.
Divide the area into regular shapes and find their areas then add them all up together
