1. Given parameters :

   • The length of a rectangular sheet of paper is 15 cm
   • The breadth of the sheet is 12 cm

   To find :

   • The perimeter of the sheet

   Formula used :

   • Perimeter of rectangle = 2 ( length + breadth )

   Solution :

   • Length = 15 cm
   • Width / Breadth = 12 cm

   Put the values in the formula ,

   • Perimeter of rectangle = 2 ( 15 + 12 )
   • Perimeter = 2 × 27
   • Perimeter = 54 cm

2. Given :

   • Length of rectangular sheet of paper = 15 cm
   • Breadth of rectangular sheet of paper = 12 cm

   To Find :

   • Perimeter of rectangular sheet of paper = ?

   Solution :

   As, we have :

   • Length of rectangular sheet of paper = 15 cm
   • Breadth of rectangular sheet of paper = 12 cm

   So, to find perimeter we have a formula :

   [Perimeter of rectangle = 2 (length + breadth)]

   So, For perimeter of given rectangular sheet of paper :

   Perimeter = 2 (15 cm + 12 cm)

   = 2 (27 cm)

   = 2 × 27 cm

   = 54 cm

   Hence, Perimeter of given rectangular sheet of paper is 54 cm.
