Area of Isosceles Triangle Calculator

Calculate Area





Formula

The formula to calculate the Area of an Isosceles Triangle is:

\[ A = \frac{S_{\text{Base}}}{2} \cdot \sqrt{S_{\text{Legs}}^2 - \frac{S_{\text{Base}}^2}{4}} \]

Definition

The area of an isosceles triangle is the amount of space or region enclosed by it in a two-dimensional space. The base is the third and unequal side of the isosceles triangle, and the legs are the two equal sides of the isosceles triangle.

Example Calculation

Let's assume the following values:

Using the formula:

\[ A = \frac{6}{2} \cdot \sqrt{9^2 - \frac{6^2}{4}} \approx 25.4558 \]

The Area is approximately 25.4558 Square Meters.
