Answer:-
Finding the perimeter of a triangle is simple—just add up the lengths of all three sides. If the sides are labeled as a, b, and c, the formula is: Perimeter = a + b + c For example, if a triangle has sides measuring 5 cm, 7 cm, and 10 cm, its perimeter would be 5 + 7 + 10 = 22 cm. If you only know some sides and angles, you might need the Pythagorean theorem (for right triangles) or the law of cosines. But in most cases, just sum up the sides to find the perimeter!
