To find the area of a triangle find the base and the height of the triangle. Then multiply the base by the height, then divide by 2. To find the perimiter of a triangle add together the outside edge of the triangle. To find the area of a triangle find the base and the height of the triangle. Then multiply the base by the height, then divide by 2. To find the perimiter of a triangle add together the outside edge of the triangle.
The perimeter of a shape such as a polygon is the sum of its sides.
Add the four sides.

4 sides so 20x + 8
A triangle (as you may know) by definiition has 3 sides; if you add up the lengths of all 3 sides, that total is called the perimeter.

Perimiter is all of the sides of an object added together. (ie., length of a + length of b + length of c equals the perimiter of a triangle (a+b+c+d=P ♦)
