Answer:
31.2
Step-by-step explanation:
Perimeter of Shape A: 20
Shown side of Shape A: 2
20 ÷ 2 = 10
So.....
3.12 x 10 = 31.2
Perimeter of shape B: 31.2
31.2 units
The ratio of perimeters is the same as the ratio of side lengths between the similar figures.
P/20 = 3.12/2.0
P = 20(3.12/2.0) = 3.12(20/2.0) = 3.12(10)
P = 31.2
The perimeter of Figure B is 31.2 units.
