Introduction

The Pentagon, located in Washington, D.C., is an iconic building known for its unique shape and massive size. With each outside wall measuring 921 feet in length, the question arises: what is the perimeter of the Pentagon? In this article, we will delve into the world of mathematics to find the answer.

Understanding the Pentagon's Shape

The Pentagon is a five-sided polygon, with each side being a straight line. To calculate the perimeter, we need to add up the lengths of all five sides. However, the Pentagon's shape is not a simple rectangle or square, making it a bit more complex.

Calculating the Perimeter

To calculate the perimeter, we can use the formula:

Perimeter = Sum of all side lengths

In this case, we have five sides, each measuring 921 feet. Therefore, the perimeter can be calculated as:

Perimeter = 5 x 921 feet

Solving the Problem

Now, let's solve the problem using the formula:

Perimeter = 5 x 921 feet Perimeter = 4605 feet

Conclusion

The perimeter of the Pentagon is 4605 feet. This is the correct answer, and it can be verified by using the formula and the given information.

Discussion

The question provided four options: A) 3,684 ft, B) 2,663,476.74 ft, C) 5,526 ft, and D) 4,605 ft. We have already determined that the correct answer is D) 4,605 ft. Let's analyze the other options:

Option A) 3,684 ft is incorrect because it is less than the actual perimeter.
Option B) 2,663,476.74 ft is also incorrect because it is much larger than the actual perimeter.
Option C) 5,526 ft is incorrect because it is larger than the actual perimeter.

Mathematical Concepts

This problem involves basic mathematical concepts, including:

Perimeter: The distance around a shape.
Polygon: A shape with multiple sides.
Side length: The distance between two adjacent vertices of a shape.

Real-World Applications

Understanding the perimeter of the Pentagon has real-world applications in various fields, including:

Architecture: Architects use perimeter calculations to design buildings and ensure that they meet building codes and regulations.
Engineering: Engineers use perimeter calculations to design and build structures, such as bridges and roads.
Surveying: Surveyors use perimeter calculations to measure the distance around a property or a piece of land.
