Introduction

In geometry, an equilateral triangle is a triangle in which all three sides are equal in length. This property makes it a fundamental concept in mathematics, with numerous applications in various fields, including physics, engineering, and architecture. When dealing with equilateral triangles, understanding the relationship between the perimeter and the side length is crucial. In this article, we will delve into the world of equilateral triangles and explore how to find the length of each side given the perimeter.

The Perimeter of an Equilateral Triangle

The perimeter of a polygon is the sum of the lengths of all its sides. For an equilateral triangle, since all three sides are equal, the perimeter can be calculated by multiplying the length of one side by 3. Mathematically, this can be represented as:

P = 3s

where P is the perimeter and s is the length of each side.

Given Perimeter and Unknown Side Length

We are given that the perimeter of the equilateral triangle is $15x^3 + 33x^5$ feet. Using the formula for the perimeter of an equilateral triangle, we can set up an equation to find the length of each side:

$15x^3 + 33x^5$ = 3s

Solving for Side Length

To find the length of each side, we need to isolate the variable s. We can start by dividing both sides of the equation by 3:

s = ($15x^3 + 33x^5$) / 3

Simplifying the Expression

To simplify the expression, we can factor out the common term $x^3$ from the numerator:

s = ($15x^3 + 33x^5$) / 3 s = $x^3(15 + 11x^2)$ / 3

Further Simplification

We can further simplify the expression by dividing the numerator and denominator by $x^3$:

s = ($15 + 11x^2$) / 3

Multiplying Both Sides by 3

To eliminate the fraction, we can multiply both sides of the equation by 3:

3s = $15 + 11x^2$

Dividing Both Sides by 3

Finally, we can divide both sides of the equation by 3 to isolate the variable s:

s = ($15 + 11x^2$) / 3

Conclusion

In conclusion, the length of each side of the equilateral triangle is ($15 + 11x^2$) / 3 feet. This can be rewritten as $5 + 11x^2$ feet, which is the correct answer.

Final Answer

The final answer is $5 + 11x^2$ feet.
