Answer:
irrational
Step-by-step explanation:
You can't multiply it with 2 same digits
Answer with explanation:
Let the length of rectangular fence = x meters
Let the width of the rectangular fence = y meters
Thus

Now Let the total cost to construct the fence be 'C' can be obtained if we construct the shorter side with material with cost $12 per foot

Using value of x from the equation i into equation ii we get

hence to minimize the cost we differentiate both sides with respect to 'y' and equate the result to zero thus we get

Thus 
Thus value of length = 11.114 feet and value of width = 18.894 feet.
