Area of a Triangle: Formula & Examples
Introduction
Welcome to our comprehensive guide on finding the area of a triangle. In this article, we will break down the formula, provide clear examples, and give you step-by-step instructions to calculate the area of any triangle. Understanding the concept of finding the triangle's area is a valuable skill in the field of business and consumer services.
Understanding the Formula
Before we dive into the specific steps, let's first understand the formula for finding the area of a triangle. The formula is:
Area = (Base × Height) / 2
Here, the base refers to the length of the triangle's base, while the height is the perpendicular distance from the base to the opposite vertex. By plugging in these values into the formula, we can easily calculate the area of the triangle.
Examples
To further illustrate the concept, let's go through a few examples of calculating the area of triangles.
Example 1: Finding the Area of a Right Triangle
Consider a right triangle with a base of 5 units and a height of 3 units. To find its area, we can use the formula as follows:
Area = (5 × 3) / 2 = 7.5 square units
Therefore, the area of this right triangle is 7.5 square units.
Example 2: Finding the Area of an Equilateral Triangle
Now, let's calculate the area of an equilateral triangle with a side length of 6 units. Since an equilateral triangle has equal sides and angles, we can determine the height by using the Pythagorean theorem. The formula becomes:
Area = (6 × h) / 2 = (6 × (√3/2 × 6)) / 2 = (18√3) / 2 ≈ 15.588 square units
Therefore, the area of this equilateral triangle is approximately 15.588 square units.
Step-by-Step Instructions
- Identify the length of the triangle's base.
- Determine the perpendicular distance from the base to the opposite vertex (the height).
- Apply the formula: (Base × Height) / 2.
- Calculate the result to find the area of the triangle.
By following these steps, you can easily find the area of any triangle.
