How do you work out mix shapes?

To work out mixed shapes, first break down the complex shape into simpler geometric figures (like rectangles, triangles, and circles) whose areas you can calculate easily. Measure the dimensions needed for each shape, then calculate their individual areas using the appropriate formulas. Finally, sum the areas of all the shapes to find the total area of the mixed figure, or subtract areas if there are overlapping sections. Always ensure to keep track of the units used in your calculations.
