Area Of Composite Figures Worksheet 7th Grade Pdf
As a 7th-grade math student, one of the most important concepts to understand is finding the area of composite figures. Composite figures are shapes that are made up of two or more simple shapes. These simple shapes can be combined to create more complex shapes. To find the area of composite figures, you need to break them down into simple shapes and apply the relevant formulas.
What is a Composite Figure?
A composite figure, also known as a compound shape, is a shape that is made up of two or more simple shapes. Simple shapes include squares, rectangles, triangles, circles, and other polygons. Composite figures can be irregular in shape and may be made up of different types of simple shapes.
For example, a composite figure could be a shape made up of a rectangle and a triangle, or a shape made up of two semi-circles and a rectangle. To calculate the area of a composite figure, you need to break it down into the simple shapes that make it up. You can then calculate the area of each simple shape and add them together to find the total area of the composite figure.
How to Find the Area of Composite Figures
To find the area of composite figures, follow these steps:
- Break the composite figure down into simpler shapes.
- Calculate the area of each simple shape.
- Add up the areas of all the simple shapes to find the total area of the composite figure.
Let's take an example to illustrate this. Suppose you have a composite figure that looks like a rectangle with a triangle on top.
To find the area of this composite figure, we need to break it down into two simpler shapes:
- A rectangle with a length of 10 units and a width of 6 units.
- A triangle with a base of 10 units and a height of 4 units.
Now, we can calculate the area of each of these shapes:
- The area of the rectangle is 60 square units (10 x 6).
- The area of the triangle is 20 square units ((10 x 4) / 2).
Finally, we add up the areas of the two shapes to find the total area of the composite figure:
Total Area = Area of Rectangle + Area of Triangle = 60 + 20 = 80 square units
