If the perimeter of an equilateral triangle is 26 mm, then its side is 26: 3 = 26/3 mm.
Find the perimeter of a square with the same side length.
26/3 * 4 = 104/3 mm.
If the side of the triangle and the side of the square are 26 mm, then the perimeter of the triangle is 26 * 3 = 78 mm, and the perimeter of the square is 26 * 4 = 104 mm.
