Perimeter worksheet for kids with four geometric figures to calculate.

To find the perimeter of each figure, we need to add up the lengths of all the sides.

Let’s go one by one:

---

Figure 1: Rectangle

Sides: 8m, 5m, 8m, 5m
Add them:
8 + 5 = 13
13 + 8 = 21
21 + 5 = 26m

✔ Perimeter = 26 meters

---

Figure 2: Triangle

Sides: 5m, 7m, 9m
Add them:
5 + 7 = 12
12 + 9 = 21m

✔ Perimeter = 21 meters

---

Figure 3: Trapezoid

Sides: 3in, 9in, 10in, 9in
Add them:
3 + 9 = 12
12 + 10 = 22
22 + 9 = 31in

✔ Perimeter = 31 inches

---

Figure 4: Irregular Quadrilateral

Sides: 8ft, 8ft, 20ft, 23ft
Add them:
8 + 8 = 16
16 + 20 = 36
36 + 23 = 59ft

✔ Perimeter = 59 feet

---

Final Answer:
26m, 21m, 31in, 59ft
