Perimeter of Different Shapes Worksheet - Free Printable

Let’s solve each shape one by one. Remember, perimeter means adding up all the sides of a shape.

---

Shape 1: Rectangle

Sides: 7 cm, 2 cm, 7 cm, 2 cm
(We know opposite sides of a rectangle are equal.)

Add them:
7 + 2 = 9
9 + 7 = 16
16 + 2 = 18

✔ Perimeter = 18 cm

---

Shape 2: Triangle

Sides: 4 cm, 6 cm, 3 cm

Add them:
4 + 6 = 10
10 + 3 = 13

✔ Perimeter = 13 cm

---

Shape 3: Quadrilateral (4-sided shape)

Sides: 3 cm, 7 cm, 5 cm, 6 cm

Add them:
3 + 7 = 10
10 + 5 = 15
15 + 6 = 21

✔ Perimeter = 21 cm

---

Shape 4: Triangle

Sides: 7 m, 10 m, 11 m

Add them:
7 + 10 = 17
17 + 11 = 28

✔ Perimeter = 28 m

*(Note: This one is in meters, not centimeters — don’t forget to write “m”!)*

Shape 5: Pentagon (5-sided shape)

Sides: 6 cm, 4 cm, 7 cm, 6 cm, 4 cm

Add them step by step:
6 + 4 = 10
10 + 7 = 17
17 + 6 = 23
23 + 4 = 27

✔ Perimeter = 27 cm

---

Shape 6: Pentagon (another 5-sided shape)

Sides: 5 cm, 3 cm, 6 cm, 3 cm, 5 cm

Add them:
5 + 3 = 8
8 + 6 = 14
14 + 3 = 17
17 + 5 = 22

✔ Perimeter = 22 cm

---

Final Answer:

1) 18 cm
2) 13 cm
3) 21 cm
4) 28 m
5) 27 cm
6) 22 cm
