Calling x and y the two sizes of the rectangular field, the problem consists in finding the minimum values of x and y that give an area of

.
The area is the product between the two sizes:

(1)
While the perimeter is twice the sum of the two sizes:

(2)
From (1) we can write

and we can substitute it into (2):

To find the minimum value of the perimeter, we have to calculate its derivative and put it equal to zero:

The derivative of the perimeter is

If we require p'(x)=0, we find


And the other side is

This means that the dimensions that require the minimum amoutn of fencing are (424.26 m, 424.26 m), so it corresponds to a square field.

<em><u>Answer:</u></em>
3n = 6n + 28
<em><u>Explanation:</u></em>
The number we are dealing with is "n"
<u>We will proceed by converting the English into Math:</u>
1- Three times the number = 3 * n = 3n
2- Six times the number = 6 * n = 6n
3- 28 more than 6 times the number means that we will add 28 to the value 6n. This will give 6n + 28
<u>Finally, we are given that:</u>
3n is the same as (6n + 28). This means that they are both equal.
<u>Therefore, our equation would be:</u>
3n = 6n + 28
Hope this helps :)
Answer:
One fourth (1/4) of anything is 25%.
100% is a whole (the committe). Divide the whole (100%) by 4 to get 25%. 1/4
