The area of a triangle is equal to half the product of two sides times the sine of the included angle. Areas of Triangles The most common formula for finding the area of a triangle is K ½ bh where K is the area of the triangle b is the base of the triangle and h is the height. To find the area of a triangle multiply the base by the height and then divide by 2.
Area of a Triangle Formula The area of the triangle is given by the formula mentioned below.
Area 1 2 ab sin C Area 1 2 bc sin A Area 1 2 ca sin B. You can find the area of a triangle by multiplying the base by the height and then dividing that number by 2. Khan Academy has a nifty drag tool that lets you see how the area of a triangle is found using the rectangleparallelogram its inscribed in. Depending on which sides and angles we know the formula can be written in three ways.
