Printable primary math worksheet for math grades 1 to 6 based on ... - Free Printable

To solve the problem of finding the areas of the given squares and rectangles, we need to use the following formulas:

1. Area of a Square:
\[
\text{Area} = \text{side} \times \text{side}
\]

2. Area of a Rectangle:
\[
\text{Area} = \text{length} \times \text{width}
\]

Let's calculate the area for each shape step by step.

Shape 1:

- Shape: Square
- Side length: 3 cm
- Area:
\[
\text{Area} = 3 \, \text{cm} \times 3 \, \text{cm} = 9 \, \text{cm}^2
\]

---

Shape 2:

- Shape: Rectangle
- Length: 8 cm
- Width: 2 cm
- Area:
\[
\text{Area} = 8 \, \text{cm} \times 2 \, \text{cm} = 16 \, \text{cm}^2
\]

---

Shape 3:

- Shape: Square
- Side length: 5 cm
- Area:
\[
\text{Area} = 5 \, \text{cm} \times 5 \, \text{cm} = 25 \, \text{cm}^2
\]

---

Shape 4:

- Shape: Rectangle
- Length: 9 cm
- Width: 4 cm
- Area:
\[
\text{Area} = 9 \, \text{cm} \times 4 \, \text{cm} = 36 \, \text{cm}^2
\]

---

Shape 5:

- Shape: Square
- Side length: 7 cm
- Area:
\[
\text{Area} = 7 \, \text{cm} \times 7 \, \text{cm} = 49 \, \text{cm}^2
\]

---

Shape 6:

- Shape: Rectangle
- Length: 9 cm
- Width: 3 cm
- Area:
\[
\text{Area} = 9 \, \text{cm} \times 3 \, \text{cm} = 27 \, \text{cm}^2
\]

---

Shape 7:

- Shape: Rectangle
- Length: 7 cm
- Width: 3 cm
- Area:
\[
\text{Area} = 7 \, \text{cm} \times 3 \, \text{cm} = 21 \, \text{cm}^2
\]

---

Shape 8:

- Shape: Rectangle
- Length: 10 cm
- Width: 5 cm
- Area:
\[
\text{Area} = 10 \, \text{cm} \times 5 \, \text{cm} = 50 \, \text{cm}^2
\]

---

Shape 9:

- Shape: Square
- Side length: 9 cm
- Area:
\[
\text{Area} = 9 \, \text{cm} \times 9 \, \text{cm} = 81 \, \text{cm}^2
\]

---

Final Answers:

\[
\boxed{
\begin{array}{ccc}
9 \, \text{cm}^2 & 16 \, \text{cm}^2 & 25 \, \text{cm}^2 \\
36 \, \text{cm}^2 & 49 \, \text{cm}^2 & 27 \, \text{cm}^2 \\
21 \, \text{cm}^2 & 50 \, \text{cm}^2 & 81 \, \text{cm}^2
\end{array}
}
\]
