Let's solve each shape's perimeter step by step. The
perimeter is the total distance around the outside of a shape. We add up all the side lengths.
---
1. Blue Square
- All sides are 4 cm.
- Perimeter = 4 + 4 + 4 + 4 =
16 cm
---
2. Orange Rectangle
- Length = 6 ft, Width = 2 ft
- Perimeter = 2 × (length + width) = 2 × (6 + 2) = 2 × 8 =
16 ft
---
3. Red Triangle
- Sides: 8 inch, 8 inch, 8 inch → Equilateral triangle
- Perimeter = 8 + 8 + 8 =
24 inches
---
4. Green Parallelogram
- Opposite sides are equal: 5 m and 3 m
- Sides: 5, 3, 5, 3
- Perimeter = 5 + 3 + 5 + 3 =
16 m
---
5. Purple Trapezoid
- Sides: 6 cm, 2 cm, 9 cm, 2 cm
- Perimeter = 6 + 2 + 9 + 2 =
19 cm
---
6. Blue Right Triangle
- Sides: 7 ft, 9 ft, 3 ft
- Perimeter = 7 + 9 + 3 =
19 ft
---
7. Orange Regular Pentagon
- All sides are 9 cm
- 5 sides → 5 × 9 =
45 cm
---
8. Blue Rectangle
- Length = 7 ft, Width = 4 ft
- Perimeter = 2 × (7 + 4) = 2 × 11 =
22 ft
---
9. Red Triangle
- Sides: 10 ft, 13 ft, 13 ft
- Perimeter = 10 + 13 + 13 =
36 ft
---
