Introduction

In geometry, the relationship between the base and height of a triangle is crucial in determining its area. The area of a triangle is given by the formula: Area = (base × height) / 2. In this article, we will explore a scenario where the height of a triangle is related to its base, and we need to find the equation that models this situation.

The Relationship Between the Base and Height of the Triangle

The height of the triangle is 2 less than 5 times its base. This can be expressed as: height = 5x - 2, where x is the length of the base in feet. We are given that the area of the triangle is 12 square feet. Using the formula for the area of a triangle, we can write the equation: (base × height) / 2 = 12.

Substituting the Relationship Between the Base and Height

We can substitute the expression for the height (5x - 2) into the equation for the area of the triangle: (x × (5x - 2)) / 2 = 12. This equation represents the relationship between the base and the area of the triangle.

Simplifying the Equation

To simplify the equation, we can start by multiplying both sides by 2 to eliminate the fraction: x × (5x - 2) = 24. Next, we can distribute the x to the terms inside the parentheses: 5x^2 - 2x = 24.

Rearranging the Equation

To put the equation in standard quadratic form, we need to move the constant term to the right-hand side: 5x^2 - 2x - 24 = 0. This is the equation that models the situation.

Comparison with the Given Options

Let's compare the equation we derived with the given options:

A. $25x^2 - 10x - 24 = 0$ B. $5x^2 - 2x - 6 = 0$

Our derived equation is: $5x^2 - 2x - 24 = 0$ . This matches option A.

Conclusion

In this article, we explored the relationship between the base and height of a triangle and derived the equation that models this situation. We compared the derived equation with the given options and found that it matches option A. This equation can be used to solve for the length of the base of the triangle, given its area.
