If a triangle has sides 6 cm, 8 cm, and 10 cm, what is the perimeter?

Explanation:
Perimeter is the total length around a shape, so for a triangle you add up all three side lengths. Here the sides are 6 cm, 8 cm, and 10 cm. Add them: 6 + 8 = 14, and 14 + 10 = 24. So the perimeter is 24 cm. The other numbers don’t fit because they come from missing a side or altering the total, but with all three sides counted, you get 24. (Note: 6–8–10 is also a right triangle, but that isn’t needed to find the perimeter.)
