He need a total of 104 poles.
• Given data :
The fence is square in shape.
Number of poles in the one side of fence = 27
• Now, in the two parallel sides of the fence the total number of poles is
= 27×2
= 54 poles
• Now,in the other two parallel sides of the fence the total number pole will be 4 less than the total number of the poles in other two parallel sides, because the 4 poles in the 4 corner overlap each other in the edge of two two consecutive sides.
• So,the number of poles in the other two sides
= 54 - 4
= 50 poles
• Total number of poles = 50+54 = 104 poles (answer)
