p=64cm^2

was it helpfull

Answer 2

Given :-

• Length of Card = 20cm
• Breadth of Card = 12cm

To Find :-

• Perimeter of the Card.

Solution :-

❏ As we know that, Perimeter of Rectangle is given by [ Perimeter of Rectangle = 2 ( Length + Breadth ) ]

Putting the Values :

⟾ Perimeter of Card = 2 ( L + B )

⟾ Perimeter of Card = 2 ( 20 + 12 )

⟾ Perimeter of Card = 2 × 32

⟾ Perimeter of Card = 64cm

Thus, Perimeter of Card is 64cm
