Answer:
Step-by-step explanation:
- 7m ÷ 2 = 3.5m
- Part A: New square is 3.5-meter by 3.5-meter
- The original square's perimeter is 7x4=28-meter.
- The new square's perimeter is 3.5x4=12-meter
- Part B: The ratio is 12:28 or 3:7
- The original square's area is 7²=49 meter²
- The new square's area is 3.5²=12.25 meter²
- Part C: The ratio is 49:12.25
Answer:
Step-by-step explanation:
<u>Victoria collects:</u>
<u>Javier collects:</u>
<u>They get same amount:</u>
- 8x + 56 = 12x + 16
