Answer 1

Answer:

Step-by-step explanation:

1. 7m ÷ 2 = 3.5m
2. Part A: New square is 3.5-meter by 3.5-meter
3. The original square's perimeter is 7x4=28-meter.
4. The new square's perimeter is 3.5x4=12-meter
5. Part B: The ratio is 12:28 or 3:7
6. The original square's area is 7²=49 meter²
7. The new square's area is 3.5²=12.25 meter²
8. Part C: The ratio is 49:12.25
