Answer 2

Answer:

The formula of perimeter of square is 4×sides And the formula of the rectangle is 2×l+b

Step-by-step explanation:

Let me give you an example

The one side of an square is 5 cm . Find out it's perimeter ?

So , One side of the square is 5cm

Formula of perimeter of square is 4×sides

= 5×4 = 20

And the example of rectangle is ...

Length of an rectangle is 4cm and breath of the rectangle is 5cm . Find out it's perimeter ?

So , Length of the rectangle is 4cm

Breath of the rectangle is 5cm

Formula of perimeter of rectangle is 2×l+b

So , 2+(4×5)

= 2+20

= 22
