Let’s solve each problem one by one, step by step.

Problem 1:
Natalie runs around a park with sides:
15 feet, 10 feet, 12 feet, and 14 feet.
To find how many feet she runs, we add all the sides together — that’s the perimeter.
Step-by-step addition:
15 + 10 = 25
25 + 12 = 37
37 + 14 = 51
So, Natalie runs
51 feet.
✔ Correct answer:
a. 51 feet

Problem 2:
A picture has:
- 2 sides that are 6 inches
- 2 sides that are 10 inches
Perimeter = add all sides.
So:
6 + 6 = 12
10 + 10 = 20
12 + 20 = 32
✔ Correct answer:
c. 32

Problem 3:
A pentagon (5-sided shape) has:
- 3 sides that are 8 cm long → 3 × 8 = 24 cm
- 1 side is 11 cm
- 1 side is 6 cm
Add them up:
24 + 11 = 35
35 + 6 = 41
✔ Correct answer:
b. 41 cm

Problem 4:
An octagon has 8 sides.
Each side is 9 inches long.
So, perimeter = 8 × 9 = 72 inches
✔ Correct answer:
c. 72 inches
---
Final Answer:
1. a. 51 feet
2. c. 32
3. b. 41 cm
4. c. 72 inches
