Finding the area of a shaded region in geometric shapes can be simple if you follow these steps:
- Identify the Shapes: Determine the shapes involved, such as circles, rectangles, or triangles.
- Calculate Individual Areas: Use formulas to find areas of individual shapes. For example, area of a rectangle is length × width, and area of a circle is πr².
- Determine Shaded Region: Subtract the area of shapes that are not shaded from the total area.
- Add Multiple Regions: If there are multiple shaded areas, sum them up for the total shaded area.
| Shape | Formula |
|---|---|
| Rectangle | length × width |
| Circle | πr² |
| Triangle | ½ × base × height |
By following these steps, you can easily find the area of any shaded region within geometric shapes effectively.
