Question

Each smaller rectangle in a chocolate bar is of length 8.2 cm and breadth 6.8 cm. Find the perimeter of the chocolate bar.

Answer 1

Step-by-step explanation:

Required answer,step wise -:

Length of chocolate bar = 8.2 cm

Breadth of chocolate bar = 6.8 cm

As we know that -:

Perimeter of rectangle = 2 ( L + B )

Thus, perimeter of chocolate bar -:

Length of chocolate bar = 8.2 cm

Breadth of chocolate bar = 6.8 cm

Perimeter of chocolate bar = 2 ( L + B ) cm

= 2 ( 8.2 + 6.8 ) cm

= 2 × 15 cm

= 30 cm

Thus,the perimeter of the chocolate bar is 30 cm.

Answer 2

Answer:

76.4

Step-by-step explanation:

L = 8.2 CM

B = 6.8 CM

=> 8.2x6 = 24.6

=> 6.8x4 = 13.6

=> Perimeter = 2(24.6+13.6)

=> 2*38.2 = 76.4

THEREFORE, THE ANSWER IS 76.4.
