25 Απρ 2016 · Finding the perimeter and area of a triangle. Mathematicians have no special formula for finding the perimeter of a triangle — they just add up the lengths of the sides. To find the area of a triangle, you need to know the length of one side — the base (b for short) — and the height(h).
