How do you find the perimeter? - Answers

The formula for finding perimeter of an object is based on the type of geometrical object.Perimeter of a Square = 4L. If one side of a square measures 2 inches then the perimeter of the square is 2 in + 2 in + 2 in + 2 in or 8 inches.lolPerimeter of a Rectangle = 2W + 2L. If the width of a rectangle measures 4 inches and the length measures 2 inches then the perimeter of the rectangle would be 2 in + 2 in + 4 in + 4 in or 12 inches.Perimeter of a Triangle = A + B + C.
