Let’s solve each problem step by step.

Perimeter Problems (add all sides):

1. Rectangle: 9 ft + 5 ft + 9 ft + 5 ft =
→ 9 + 5 = 14; 14 + 9 = 23; 23 + 5 = 28 ft

2. Triangle: 7 mm + 7 mm + 6 mm =
→ 7 + 7 = 14; 14 + 6 = 20 mm

3. Square: All sides 8 mm → 8 + 8 + 8 + 8 =
→ 8 × 4 = 32 mm

4. Parallelogram: Opposite sides equal → 8 in + 4 in + 8 in + 4 in =
→ 8 + 4 = 12; 12 + 8 = 20; 20 + 4 = 24 in

Area Problems:

5. Square: side × side → 4 in × 4 in = 16 in²

6. Rectangle: length × width → 8 ft × 3 ft = 24 ft²

7. Rectangle: 3 mm × 1 mm = 3 mm²

---

Final Answer:
1. 28 ft
2. 20 mm
3. 32 mm
4. 24 in
5. 16 in²
6. 24 ft²
7. 3 mm²
