You approximate your irregular figure lots of small figures of known shapes. For example, you can divide it into lots of thin vertical (or horizontal) stripes, each of which is approximately a rectangle.
You divide the shape into smaller shapes you can calculate, like rectangles and triangles. If the shape is irregular, you have to approximate, for example by dividing it into many narrow rectangles. This technique is called "integration".
You approximate the irregular shape with many small regular figure, for example, long and thin rectangles.
You get the area by using formulas. There is usually a specific formula to find the area of each shape. Some irregular shaps may not have a formula.
There is no standard formula. It is necessary to partition the irregular hexagon into more convenient shapes such as triangles and quadrilaterals, find their areas and sum the results.

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
the approximate area is 9.0 square miles.
A Planimeter.
You divide the shape into smaller shapes you can calculate, like rectangles and triangles. If the shape is irregular, you have to approximate, for example by dividing it into many narrow rectangles. This technique is called "integration".
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.
You approximate it with many small rectangles. This is known as integration.
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.
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.
