Answer 1

Answer:

Perimeter of B = 50 cm

Step-by-step explanation:

Have a look at the attachment

In Shape A no. of the unit sides = 12

                                Perimeter A = length of 12 unit sides

                                                     = 60 cm

                ∴ length of 1 unit side = 60/12 = 5 cm

Now

In Shape B no. of the unit sides = 10

                             ∴ Perimeter B = 5 x 10 = 50 cm
