WebSolution: We know that the perimeter of a triangle is given by. Perimeter = a + b + c, Where a, b, c = length of three sides. Therefore, For the given triangle, Perimeter = 5 cm + 4 … Web20 feb. 2024 · To find the perimeter of a triangle knowing its three sides (SSS triangle), all you have to do is add the three known sides. For example, the perimeter of a triangle with sides a = 3 cm, b = 2 cm and c = 4 cm can be calculated as follows: perimeter_SSS = a + b+ c. perimeter_SSS = 3 cm + 2 cm + 4 cm. perimeter_SSS = 9 cm blackwood pilates
