To solve the problem of finding the area of each rectangle, we use the formula for the area of a rectangle:
\[
\text{Area} = \text{length} \times \text{width}
\]
Let's calculate the area for each rectangle step by step.
---
1)
- Length: \( 8 \, \text{cm} \)
- Width: \( 3 \, \text{cm} \)
\[
\text{Area} = 8 \, \text{cm} \times 3 \, \text{cm} = 24 \, \text{square cm}
\]
Answer: \( 24 \, \text{square cm} \)
---
2)
- Length: \( 7 \, \text{ft} \)
- Width: \( 5 \, \text{ft} \)
\[
\text{Area} = 7 \, \text{ft} \times 5 \, \text{ft} = 35 \, \text{square ft}
\]
Answer: \( 35 \, \text{square ft} \)
---
3)
- Length: \( 3 \, \text{m} \)
- Width: \( 3 \, \text{m} \)
\[
\text{Area} = 3 \, \text{m} \times 3 \, \text{m} = 9 \, \text{square m}
\]
Answer: \( 9 \, \text{square m} \)
---
4)
- Length: \( 10 \, \text{in} \)
- Width: \( 4 \, \text{in} \)
\[
\text{Area} = 10 \, \text{in} \times 4 \, \text{in} = 40 \, \text{square in}
\]
Answer: \( 40 \, \text{square in} \)
---
5)
- Length: \( 9 \, \text{m} \)
- Width: \( 2 \, \text{m} \)
\[
\text{Area} = 9 \, \text{m} \times 2 \, \text{m} = 18 \, \text{square m}
\]
Answer: \( 18 \, \text{square m} \)
---
6)
- Length: \( 8 \, \text{cm} \)
- Width: \( 5 \, \text{cm} \)
\[
\text{Area} = 8 \, \text{cm} \times 5 \, \text{cm} = 40 \, \text{square cm}
\]
Answer: \( 40 \, \text{square cm} \)
---
Final Answers:
1. \( 24 \, \text{square cm} \)
2. \( 35 \, \text{square ft} \)
3. \( 9 \, \text{square m} \)
4. \( 40 \, \text{square in} \)
5. \( 18 \, \text{square m} \)
6. \( 40 \, \text{square cm} \)
\[
\boxed{24, 35, 9, 40, 18, 40}
\]
