Chapter - 10 Mensuration

1. Perimetre shapes

• = 12 cm + 16 cm + 18 cm + 10 cm + 14 cm = 71

• = 12 cm + 16 cm + 18 cm + 10 cm + 14 cm = 73

• = 12 cm + 16 cm + 18 cm + 10 cm + 14 cm = 70

• = 12 cm + 16 cm + 18 cm + 10 cm + 14 cm = 60

2. Perimetre Shapes

• 21 cm + 32 cm + 43 cm + 54 cm + 65 cm + 76 cm = 291

• 21 cm + 32 cm + 43 cm + 54 cm + 65 cm + 76 cm = 292

• 21 cm + 32 cm + 43 cm + 54 cm + 65 cm + 76 cm = 293

• 21 cm + 32 cm + 43 cm + 54 cm + 65 cm + 76 cm = 290

Formula for perimeter of rectangle

• Perimeter of a Rectangle = Sum of all sides

  
  

  = length + breadth + length + breadth

  
  

  = 4 x length + 4 x breadth

  
  

  = 2 x (length + breadth)

• Perimeter of a Rectangle = Sum of all sides

  
  

  = length + breadth + length + breadth

  
  

  = 2 x length + 2 x breadth

  
  

  = 2 x (length + breadth)

• Perimeter of a Rectangle = Sum of all sides

  
  

  = length + breadth + length + breadth

  
  

  = 8 x length + 8 x breadth

  
  

  = 2 x (length + breadth)

• Perimeter of a Rectangle = Sum of all sides

  
  

  = length + breadth

  
  

  = 2 x length + 2 x breadth

  
  

  = 2 x (length + breadth)
