How to Find the Height of a Triangle. Two Methods: Using Base and Area Equilateral Triangle. To calculate the area of a triangle you need to know its height. If this information is not given to you, you can easily calculate it based on what you do know!This article will teach you two different ways to find the height of a triangle, depending on what information you have been given.Ad.ow to Find the Height of a Triangle.

The area formula for a triangle is its base times its height divided by two. In the case of one of the triangles above it would be s x l Ã· 2. However, there are four triangles. This would make the total lateral surface area equal to four times the area of one triangle, or 4 x s x l Ã· 2.he total surface area of the pyramid is equal to the area of the base plus its lateral surface area or s 2 + 2sl. So, given the base length of the pyramid, s, and its slant height, l, the total surface area is not a difficult computation.
