What is the formula of the area and perimeter of a triangle?

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.
