Introduction

In mathematics, composite figures are shapes that consist of two or more basic geometric shapes, such as rectangles, triangles, and circles. These figures can be complex and require a combination of mathematical concepts to find their area. In this article, we will explore how to find the area of a composite figure using the given dimensions.

Understanding Composite Figures

A composite figure is a shape that is made up of two or more basic shapes. These shapes can be connected in various ways, such as by sharing a common side or by overlapping. To find the area of a composite figure, we need to break it down into its individual components and find the area of each one separately.

Breaking Down the Figure

The given figure consists of a rectangle with a length of 12 ft and a width of 7 ft, a triangle with a base of 5 ft and a height of 14 ft, and a rectangle with a length of 7 ft and a width of 5 ft. To find the area of the figure, we need to find the area of each of these components and then add them together.

Finding the Area of the First Rectangle

The area of a rectangle is found by multiplying its length by its width. In this case, the length of the first rectangle is 12 ft and its width is 7 ft.

# Calculate the area of the first rectangle
length = 12
width = 7
area_rectangle_1 = length * width
print("The area of the first rectangle is:", area_rectangle_1)

Finding the Area of the Triangle

The area of a triangle is found by using the formula: Area = (base × height) / 2. In this case, the base of the triangle is 5 ft and its height is 14 ft.

# Calculate the area of the triangle
base = 5
height = 14
area_triangle = (base * height) / 2
print("The area of the triangle is:", area_triangle)

Finding the Area of the Second Rectangle

The area of a rectangle is found by multiplying its length by its width. In this case, the length of the second rectangle is 7 ft and its width is 5 ft.

# Calculate the area of the second rectangle
length = 7
width = 5
area_rectangle_2 = length * width
print("The area of the second rectangle is:", area_rectangle_2)

Finding the Total Area of the Figure

To find the total area of the figure, we need to add the areas of the three components together.

# Calculate the total area of the figure
total_area = area_rectangle_1 + area_triangle + area_rectangle_2
print("The total area of the figure is:", total_area)

Conclusion

In this article, we have learned how to find the area of a composite figure using the given dimensions. We broke down the figure into its individual components and found the area of each one separately. We then added the areas of the components together to find the total area of the figure. This process requires a combination of mathematical concepts, including the area of rectangles and triangles.

Common Mistakes

Failing to break down the figure into its individual components.
Using the wrong formulas to find the area of each component.
Not adding the areas of the components together to find the total area of the figure.

Conclusion

In conclusion, finding the area of a composite figure requires a combination of mathematical concepts and a step-by-step approach. By breaking down the figure into its individual components and using the correct formulas, we can find the total area of the figure. This process is essential in various real-world applications, and it's crucial to avoid common mistakes to ensure accurate results.
