How to solve area of a triangle
WebArea = 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 = 1 2 bc sin … WebExample 1: Using the illustration above, take as given that b = 10 cm, c = 14 cm and α = 45°, and find the area of the triangle. In this case the SAS rule applies and the area can be calculated by solving (b x c x sinα) / 2 = (10 x …
