Which formula represents the perimeter of a triangle?

1/2 bh
A + B + C
2(L + W)
LW

The correct answer is: A + B + C

The formula that represents the perimeter of a triangle is the sum of the lengths of all its sides. For a triangle with sides labeled as A, B, and C, the perimeter is calculated by adding these three side lengths together. Thus, the correct formula for finding the perimeter of a triangle is A + B + C, which represents this total distance around the triangle. Other choices correspond to different mathematical concepts: 1/2 bh refers to the area of a triangle, where b is the base and h is the height. The formula 2(L + W) is used to find the perimeter of a rectangle, where L stands for length and W stands for width. Finally, LW represents the area of a rectangle, combining length and width to find the total space within the rectangle. Each of these choices serves a different purpose in geometry, underscoring why A + B + C correctly defines the perimeter of a triangle.
