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)
