Please answer what is the perimeter of figure b

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

Step-by-step explanation:

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.

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
