split up the complex figure into regions whose area you can calculate.

Sometimes splitting the figure up into triangles is a good idea.

To find the area of a complex figure, you can use the method of breaking down the figure into simpler shapes whose areas you know how to calculate. This method is called decomposition or splitting.

Here are the general steps to follow:

1. Identify the different shapes within the complex figure: Start by visually inspecting the figure and identifying the simpler shapes it is composed of, such as rectangles, triangles, circles, or combinations of these shapes.

2. Break down the complex figure: Divide the complex figure into these simpler shapes, making sure that the shapes don't overlap and that all parts of the complex figure are covered.

3. Calculate the area of each individual shape: Use the appropriate formulas to calculate the areas of the simpler shapes. For example, the area of a rectangle is calculated by multiplying its length by its width, while the area of a triangle is calculated by multiplying its base length by half of its height.

4. Add up the areas of the individual shapes: Sum up the areas of all the simpler shapes you have calculated in the previous step. This will give you the total area of the complex figure.

It's important to note that accurate measurements and careful calculations are crucial for obtaining correct results. Additionally, if the complex figure is irregularly shaped or has curved boundaries, you may need to use advanced methods such as integration or approximation techniques to find the area.

By following these steps, you can find the area of complex figures by decomposing them into simpler shapes and calculating their individual areas.
