What is the formula for calculating the perimeter of a triangle?

Sum of lengths of sides
bh
1/2 h(a + b)
2(3.14)(r)

The correct answer is: Sum of lengths of sides

The perimeter of a triangle is determined by adding together the lengths of all three sides. This means that if you have a triangle with sides of length ‘a’, ‘b’, and ‘c’, the formula for calculating the perimeter would be: perimeter = a + b + c. Therefore, the correct choice indicates this additive approach, which is fundamental to understanding the perimeter of any polygon. The other options represent formulas relevant to different geometric concepts. For instance, the option related to "bh" pertains to the area calculation of a rectangle, while "1/2 h(a + b)" is a formula for determining the area of a trapezoid. Lastly, the formula "2(3.14)(r)" describes the circumference of a circle rather than a triangle. This context reinforces that the correct choice specifically addresses the perimeter of a triangle.
