That depends on the size of the angles which, in turn, determines the geometry of the triangle.
If the perimeter of a triangle is 234 cm, then the sum of the lengths of all three sides is 234 cm. Since a triangle has three sides, each side would be one-third of the perimeter. Therefore, each side of the triangle would be 234 cm divided by 3, which equals 78 cm.
Each side measures 5 m
The perimeter of a triangle is the sum of its 3 sides
The perimeter of an equilateral triangle with a side length of 4 inches is 12 inches. Each side of an equilateral triangle is equal in length, so the perimeter is found by multiplying the side length (4 inches) by 3.
