To solve the problem of finding the perimeter of each triangle, we need to add up the lengths of all the sides of each triangle. Let's go through each triangle step by step.
Triangle a:
- Sides: 4 cm, 6 cm, 8 cm
- Perimeter = \( 4 + 6 + 8 = 18 \) cm
Triangle b:
- Sides: 5 cm, 8 cm, 10 cm
- Perimeter = \( 5 + 8 + 10 = 23 \) cm
Triangle c:
- Sides: 6 cm, 8 cm, 3 cm
- Perimeter = \( 6 + 8 + 3 = 17 \) cm
Triangle d:
- Sides: 5 cm, 5 cm, 5 cm (Equilateral triangle)
- Perimeter = \( 5 + 5 + 5 = 15 \) cm
Triangle e:
- Sides: 4 cm, 4 cm, 3 cm
- Perimeter = \( 4 + 4 + 3 = 11 \) cm
Triangle f:
- Sides: 3 cm, 6 cm, 7 cm
- Perimeter = \( 3 + 6 + 7 = 16 \) cm
Final Answers:
- Triangle a: \( \boxed{18} \) cm
- Triangle b: \( \boxed{23} \) cm
- Triangle c: \( \boxed{17} \) cm
- Triangle d: \( \boxed{15} \) cm
- Triangle e: \( \boxed{11} \) cm
- Triangle f: \( \boxed{16} \) cm
These are the perimeters of the given triangles. Each step involves simply adding the lengths of the sides of the triangle.
