Question

A farmer built a fence around his 17 cows in square shaped he used 27 fence poles on each sude of the square how many poles did he need together

Answer 1

The total no of poles used by the farmer= 27*4 = 108poles.

Hope it helps.

Answer 2

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)
