A farmer has 400 feet of fencing she would like to use to make a rectangular enclosure. She would like to maximize the area of the enclosure. The graph below shows the square footage of the enclosure, depending on the length of it.
Enclosure with 400-foot Perimeter
12,000
10,000
8,000
Area (square feet)
6,000
4,000
2,000
0
200
50 100 150
Length of Enclosure (feet)

100 feet would make the enclosure the longest

Step-by-step explanation:

The graph shows that at 100 feet the line is at its highest point.

r = 78539458390583095803458309458039485093485 or just 3

step-by-step explanation:

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
