Show answer & explanation
Correct answer: B
Key idea: each required piece is 35 m × 1 m, and the cloth is 135 m × 35 m, so pieces run along the 135 m length.
Steps to solve:
Calculate number of pieces: total area ÷ area of one piece = (135 × 35) ÷ (35 × 1) = 135 pieces.
Determine number of cuts: to get 135 pieces you make one fewer cut, so cuts = 135 − 1 = 134 cuts.
Compute total time: each cut takes 7 seconds, so total time = 134 × 7 = 938 seconds.
Answer: 938 seconds
