Area of a Triangle Formula. The area of a triangle [latex]A [/latex] is half the product of its base [latex]b [/latex] and its height [latex]h [/latex]. The height of a triangle is also known as the altitude. This formula works only if the base is perpendicular to the height. Methods to Find the Area of a Triangle. Area of a triangle can be found using three different methods. The three different methods are discussed below. Method 1. When the base and altitude of the triangle are given. Area of the triangle, A = bh/2 square units. Where b and h are base and altitude of the triangle, respectively. Method 2 Pyramids and pyramid-like figures. Volume pyramid = 1 3 ( base area) ⋅ ( height) We also measure the height of a pyramid perpendicularly to the plane of its base. Because of Cavalieri's principle, the same volume formula works for right and oblique pyramid-like figures. We start with this formula: Area = ½ × base × height. We know the base is c, and can work out the height: the height is b × sin A. So we get: Area = ½ × (c) × (b × sin A) Which can be simplified to: Area = 12 bc sin A. By changing the labels on the triangle we can also get: Area = ½ ab sin C; Area = ½ ca sin B; One more example:
