Nadia wants to enclose a square garden with fencing. it has an area of 141 square feet. to the nearest foot, how much fencing will she need?

 Nadia needs 47 feet of fencing.

Step-by-step explanation:  Given that Nadia wants  to enclose a square garden with fencing. It has an area of 141 square feet.

We are to find the quantity of the fencing needed.

Let x represents the side length of the square garden.

Then, according to the given information, we have

Since x is the length, so it cannot be negative.

That is, x = 11.87 feet.

Therefore, the quantity of fencing that is needed is given by

To the nearest foot, the total fencing needed is 47 feet.

Thus, Nadia needs 47 feet of fencing.

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
