To find the perimeter of each figure, we need to add up all the side lengths. Perimeter is just the total distance around the shape.
---
First Figure (Rectangle):
Sides: 8m, 5m, 8m, 5m
Add them: 8 + 5 + 8 + 5 = 26
Perimeter =
26 meters
---
Second Figure (Triangle):
Sides: 7m, 8m, 9m
Add them: 7 + 8 + 9 = 24
Perimeter =
24 meters
---
Third Figure (Trapezoid):
Sides: 9in, 3in, 9in, 10in
Add them: 9 + 3 + 9 + 10 = 31
Perimeter =
31 inches
---
Fourth Figure (Irregular Shape):
Sides: 7 ft, 8 ft, 23 ft, 20 ft
Wait — let’s check the shape. It has four sides shown: top = 7 ft, left = 8 ft, bottom = 23 ft, slanted right = 20 ft.
But is that all? Looking at the grid, it seems like a quadrilateral with those four sides labeled. So we add them directly.
7 + 8 + 23 + 20 = 58
Perimeter =
58 feet

Let me double-check each:
- Rectangle: 8+5+8+5 → 13+13=26
✔
- Triangle: 7+8+9 → 15+9=24
✔
- Trapezoid: 9+3+9+10 → 12+19=31
✔
- Irregular: 7+8+23+20 → 15+43=58
✔
All correct.
Final Answer:
26 meters, 24 meters, 31 inches, 58 feet
