The correct answer is: 6.8 cm
Step by step explanation:
○ Given:
A chocolate bar is cut exactly in half
Sara got a 3.4 cm long piece.
○ Step 1:

∴ Alex also get 3.4 cm long piece.
○ Step 2:
○ Length of chocolate bar
length of chocolate bar = length of Alex’s piece + length of Sara’s piece
length of chocolate bar = 3.4 + 3.4
