Perimeter of a triangle = (length of the first side) plus (length of the second side) plus (length of the third side)
You find the perimeter of a triangle by adding all the sides. There is no special rule for finding the perimeter.
The formula for finding out perimeters of shapes is length+length+height+height=perimeter or what else you can do is (lengthx2)+(heightx2)=PERIMETER
Lengths of: equal side+equal side+base = perimeter
Perimeter = 4*n whereas n is the length of its side
the formula is 1side multiply by 3
Perimeter of a triangle = (length of the first side) plus (length of the second side) plus (length of the third side)
It is not in all but a trivial sense - that they are both to do with finding the perimeter!

You multiply the base and the height and then you divide the answers of that by 2. :)
For finding the area of triangle with the help of Heron's formula: [s(s-a)(s-b)(s-c)]1/2 where a,b,c are sides of the triangle and s=1/2 of perimeter of the triangle
a + b + c
Perimeter = sum of lengths of sides.
The perimeter formula of a triangle is the sum of the lengths of all three sides. Mathematically, it can be expressed as P = a + b + c, where P is the perimeter and a, b, and c are the lengths of the three sides of the triangle.
Perimeter of a triangle = (length of side #1) + (length of side #2) + (length of side #3)
Area = 0.5 x base x height Perimeter = side 1 + side 2 + side 3 Formula for Area of a triangle is A = bh/2, where A is Area, b is base, and h is heigth. Formula for finding the perimeter is P = s1 + s2 + s3, where s represent side, or P = AB + BC + AC where the letters represent the sides.
Add the lengths of each side together to get the perimeter.
