Introduction

In geometry, a pentagon is a polygon with five sides. When it comes to calculating the perimeter of a pentagon, we need to consider the length of each side. In this article, we will explore how to calculate the perimeter of a scale model of a building shaped like a pentagon, given that each of the five outermost walls is 3 feet long.

Understanding the Problem

The problem states that we have a scale model of a building shaped like a pentagon, with each of the five outermost walls measuring 3 feet long. To calculate the perimeter of the scale model, we need to understand that the perimeter of a polygon is the sum of the lengths of all its sides.

Calculating the Perimeter

Since each of the five outermost walls is 3 feet long, we can calculate the perimeter by multiplying the length of one side by the total number of sides. In this case, we have:

Perimeter = Number of sides × Length of one side Perimeter = 5 × 3 feet Perimeter = 15 feet

Why the Perimeter is 15 Feet

The perimeter of the scale model is 15 feet because we have five sides, each measuring 3 feet long. When we multiply the number of sides by the length of one side, we get the total perimeter of the pentagon.

Real-World Applications

Calculating the perimeter of a pentagon has real-world applications in architecture, engineering, and design. For example, when designing a building, architects need to calculate the perimeter of the building to determine the amount of materials needed for the walls, windows, and doors.

Conclusion

In conclusion, the perimeter of the scale model of a building shaped like a pentagon is 15 feet. This is calculated by multiplying the number of sides (5) by the length of one side (3 feet). Understanding how to calculate the perimeter of a pentagon is essential in various fields, including architecture, engineering, and design.

Additional Examples

Here are a few more examples of calculating the perimeter of a pentagon:

If each side of the pentagon is 4 feet long, the perimeter would be: 5 × 4 feet = 20 feet
If each side of the pentagon is 2 feet long, the perimeter would be: 5 × 2 feet = 10 feet

Tips and Tricks

When calculating the perimeter of a pentagon, remember to multiply the number of sides by the length of one side. This will give you the total perimeter of the polygon.
