Area of composite figures QuickChek seventh grade
To find the area of a composite figure, you need to break it down into simpler shapes (like rectangles, triangles, circles, etc.) and then find the area of each individual shape before adding them together to get the total area of the composite figure.
Here are the general steps to find the area of a composite figure:
1. Identify the simpler shapes that make up the composite figure.
2. Break down the composite figure into these simpler shapes.
3. Find the area of each individual shape using the appropriate formula (e.g., for rectangles, area = length x width; for triangles, area = 1/2 x base x height; for circles, area = π x radius^2).
4. Add up the areas of all the individual shapes to get the total area of the composite figure.
Remember to pay attention to any overlapping or shared sides between the shapes and make sure to double-count any shared sides when calculating the total area.
It may also be helpful to draw a diagram of the composite figure with its individual shapes labeled and their dimensions given to help you visualize and organize the calculation process.
