They are many ways to find the formula of a triangle. Base times height divided by 2
K, well there is no surface area of a triangle, because a triangle is a 2s figure. Surface area is for a 3d figure. To find the regular area of a triangle the formula is 1/2 of the base X the height :) gl :P
Heron created a formula to find the area of any triangle given three side lengths. It is known as Heron's Formula.
Depending on the type of triangle, the main formula to find the area is base x height x 1/2
