Answer 2

Answer:

24 Cms.

Step-by-step explanation:

Given:

(Two sides of a rectangle)

So, let's assume

Length (a)  = 9 cms

Breadth (b) = 3 cms

Formula:

Perimeter of rectangle: 2(l+b)

Steps:

Perimeter of rectangle = 2(l+b)

                                      = 2(9+3)

                                      = 2(12)  (2 multiplied by 12)

                                      = 24

Therefore,

            The perimeter of the rectangle is 24 cms.
