What is the Area of a Triangle?

The area of a triangle is the amount of space enclosed within its three sides. It is measured in square units.

Methods to Calculate Triangle Area

1. Base and Height Method: Area = 1/2 × base × height
2. Heron's Formula (Three Sides): Area = √(s(s-a)(s-b)(s-c)), where s = (a+b+c)/2
3. Two Sides and Included Angle Method: Area = 1/2 × side1 × side2 × sin(included angle)

Example Calculation

Let's calculate the area of a triangle with base 6 units and height 4 units:

1. Area = 1/2 × base × height
2. Area = 1/2 × 6 × 4
3. Area = 12 square units
