Answer:
#5: 80mm, #6: 50yd, #7: 36m, #8: 32ft
Step-by-step explanation:
For #5:
The ratio between the two shapes is 24/15 = 8/5, based on the corresponding sides.
So, multiplying 8/5 with the smaller shape's perimeter of 50 would give you 80mm, which is the bigger shape's perimeter.
For #6:
The ratio between the two shapes is 15/9 = 5/3, based on the corresponding sides.
So, multiplying 5/3 with the smaller shape's perimeter of 30 would give you 50yd, which is the bigger shape's perimeter.
For #7:
The ratio between the two shapes is 12/4 = 3, based on the corresponding sides (You can also check this with 15/5).
So, multiplying 3 with the smaller shape's perimeter of 12 would give you 36m, which is the bigger shape's perimeter.
For #8:
The ratio between the two shapes is 12/21 = 4/7, based on the corresponding sides.
So, multiplying 4/7 with the bigger shape's perimeter of 56 would give you 32ft, which is the smaller shape's perimeter.
Hope this helps! Have a nice day!
