The most commonly used formula for the area of a triangle is where A is the area b is the length of the triangles base and h is the height of the triangle drawn perpendicular to that base. The height of a triangle is the perpendicular distance from a vertex to the base of the triangle. Where p is half the perimeter or Try thisDrag the orange dots to reshape the triangle.
Area of a Triangle A ½ b h square units where b and h are the base and height of the triangle respectively.
In geometry Herons formula sometimes called Heros formula named after Hero of Alexandria gives the area of a triangle when the length of all three sides are known. Which of the following is the same equation solved. 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. A more detailed explanation in text and video of each area formula.
