<h3><u>Answer:</u></h3>

Hence, the amount of fencing needed to surround the walkway is:

42 ft.

<h3><u>Step-by-step explanation:</u></h3>

It is given that:

A garden that is 5 t. by 6 ft. has a walkway that is 2.5 ft. wide around it.

Hence, the fencing is to be done around a garden whose dimensions:

(5+2.5+2.5)ft. by (6+2.5+2.5)ft.

= 10 ft by 11 ft.

Hence, the amount of fencing which is to be done is equal to the perimeter of the garden.

We know that the garden with walkway is in the shape of a rectangle with:

Length=10 ft.

and width=11 ft.

Hence, Perimeter of garden=2(10+11)

                                              =2×21

                                             = 42 ft.

Hence, the amount of fencing needed to surround the walkway is:

42 ft.

See diagram

so the length and width of the outside walkway is 5+2.5+2.5 and 6+2.5+2.5 or 10 and 11

the perimiter=2(L+W)=2(10+11)=2(21)=42ft


need 42 ft of fencing

german
If I understand what you are asking, you can use the median as an average since it is not affected by the mean ( median is a measure of center).  Since a mean is affected by outliers, it might lower the score if there are very low outliers. But note that if there are outliers way <em>greater </em>it can increase the average. You can use the Inter Quartile Range if shown on a box plot ( measure of variability).

Answer:

hello :  

(g/f)(3) = g(3)/f(3)

but : g(3) =3(3)+2 = 11

f(3) 2(3)-4 = 2

g/f)(3) = 11/2
