To solve this problem, remember that the perimeter of a triangle is equal to the sum of the lengths of all its sides. Since in an equilateral triangle all sides are equal, then P = 3a. We calculate what the perimeter of the triangle is, knowing that the side is 5.2 cm.
P = 3 * 5.2 = 15.6 centimeters.
Answer: 15.6 centimeters.
