What this formula means in simpler terms is that to find the perimeter of a triangle you just add together the lengths of each of its 3 sidesStep 2 Look at your triangle and determine the lengths of the three sides. So in this case if I were to walk around the outside or maybe a humans too big if an awesome little ant was to walk all the way around the outside of this figure how far she walked would be the perimeter. Use the distance formula to find the length of two of the sides.
Finding perimeter using distance formula.
PERIMETER is the distance or length around a shape. The distance formula is used to find the distances between vertices then these distances are used to find the perimeter and area of the triangle. P p3a b - 3a b a 3b Quadrilateral Trapezoid perimeter formula. Perimeter is the distance all the way around the outside of a shape.
