The area of irregular sections can be calculated using various methods such as breaking it down into simpler shapes and summing their areas.

• Break down the irregular section into simpler shapes such as rectangles, triangles, or circles.

• Calculate the area of each simpler shape using the appropriate formula (e.g. area of rectangle = length x width, area of triangle = 0.5 x base x height).

• Sum up the areas of all the simpler shapes to get the total area of the irregular section.
