Question
A farmer built a fence around his square plot. He used 27 fence poles on each side of the square. How many poles did he need altogether ?
Answer: Option B
Since each pole at the corner of the plot is common to its two sides, so we have :
Total number of poles needed = 27 x 4 - 4 = 108 - 4 = 104.
