(a) We know that the perimeter of the given triangle = The sum of all sides of the triangle ∴ Perimeter of the triangle = 3 cm + 4 cm + 5 cm = 12 cm (b) We know that the perimeter of the given triangle = Sum of all the sides of the triangle = (9 + 9 + 9) = 27 cm (c) Perimeter of the given isosceles triangle = Sum of all the sides of the triangle = (8 + 8 + 6) cm = 22 cm
