Question

Length of a rectangle is 12 cm and breadth is 4 cm less than the length.
Find the perimeter of the rectangle.​

Answer 1

Answer:

40

Step-by-step explanation:

given

   length(l)=12cm

   breadth(b) = l-4

                 =12-4

                 =8cm

 perimeter = 2*(l + b)

                    = 2* (12 + 8)

                    = 2* 20

                    =40cm

Answer 2

Answer:

40 cm is the Perimeter

Step-by-step explanation:

Length = 12 cm

Breadth = Length - 4 cm ( over here )

So Breadth = 12 cm - 4 cm

                   = 8 cm

So Breadth = 8 cm and Length = 12 cm

--------------------------------------------------------------------------------------------------------------

We know that Breadth = 8 cm and Length = 12 cm

So Perimeter = ( L + B ) * 2

                      = ( 12 cm + 8 cm ) *2

                      = 20 cm * 2

                      = 40 cm

Ans : The perimeter of the rectangle is 40 cm.
