In any triangle, the sum of the lengths of the three sides is always greater than the length of the longest side. However, if you are asking about the specific total when you add the lengths of the three sides together, it simply depends on the measurements of those sides. Unlike shapes like squares or rectangles, where specific formulas or constants might apply, triangles can vary in size and shape.
For instance, if you have a triangle with side lengths of 3 cm, 4 cm, and 5 cm, the total would be:
3 cm + 4 cm + 5 cm = 12 cm
So, the side lengths of a triangle can add up to any value, depending on the actual lengths of the sides. There is no fixed sum for triangles; it is always the total of the individual side lengths you have.
