Let’s solve each problem step by step. We’re scaling rectangles — that means we multiply both the length and width by the given scale factor to get the new dimensions.

Problem 1:
Original rectangle: 4.3 × 2.7
Scale it up by
9 times.
New length = 4.3 × 9 = 38.7
New width = 2.7 × 9 = 24.3
→ New dimensions:
38.7 × 24.3
---
Problem 2:
Original rectangle: 5.3 × 6.7
Scale it up by
4 times.
New length = 5.3 × 4 = 21.2
New width = 6.7 × 4 = 26.8
→ New dimensions:
21.2 × 26.8
---
Problem 3:
Original rectangle: 6.9 × 5.2
Scale it up by
4 times.
New length = 6.9 × 4 = 27.6
New width = 5.2 × 4 = 20.8
→ New dimensions:
27.6 × 20.8
---
Problem 4:
Original rectangle: 2.6 × 3.2
Scale it up by
9 times.
New length = 2.6 × 9 = 23.4
New width = 3.2 × 9 = 28.8
→ New dimensions:
23.4 × 28.8
---
Problem 5:
Original rectangle: 6.4 × 5.1
Scale it up by
4 times.
New length = 6.4 × 4 = 25.6
New width = 5.1 × 4 = 20.4
→ New dimensions:
25.6 × 20.4
---
Problem 6:
Original rectangle: 3.5 × 6.9
Scale it up by
4 times.
New length = 3.5 × 4 = 14.0
New width = 6.9 × 4 = 27.6
→ New dimensions:
14.0 × 27.6

Now, let’s write the answers in order for the “Answers” section on the right side of the worksheet:
1. 38.7 × 24.3
2. 21.2 × 26.8
3. 27.6 × 20.8
4. 23.4 × 28.8
5. 25.6 × 20.4
6. 14.0 × 27.6
Final Answer:
1. 38.7 × 24.3
2. 21.2 × 26.8
3. 27.6 × 20.8
4. 23.4 × 28.8
5. 25.6 × 20.4
6. 14.0 × 27.6
