Answer:

Perimeter of shape B = 50 cm

Step-by-step explanation:

Perimeter of shape A = 60 cm

Let the length of each square = x cm

Total length of free boundaries of shape A = 12x

Therefore, 12x = 60

x = 5 cm

Now length surfaces of shape B = 10x

Perimeter of shape B = 10x

                                    = 10(5)

                                    = 50 cm
