Webb20 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 WebbQ.5 The lengths of the sides of triangle ABC are 60, 80 and 100 with A= 90°.
