Before you read this article you must know, What is Perimeter Perimeter of Equilateral Triangle is to sum of length of all its sides So, Perimeter of Equilateral Triangle = side + side + side We know that in Equilateral Triangle all sides are equal, so we get; Perimeter of Equilateral Triangle = 3 side P = 3s Example 1 - In the following equilateral triangle Perimeter of Equilateral Triangle = 3 s P = 3 * 3 P = 9cm Example 2 - In the following equilateral triangle Perimeter of Equilateral Triangle = 3 s P = 3 * 5 P = 15 cm
