Hi there, so for this problem, we are told that you have 400 feet of fence into and close a rectangular lot and divided in 2 by another fence that is parallel to 1 side of the lot.
00:13
So, then we have something.
00:18
Let me just draw the situation in here.
00:22
We have initially something like this.
00:25
Okay.
00:28
And then we want to divide this by 2.
00:32
So, we just divide this here at the middle.
00:37
Okay, well, let me just move it a little bit.
00:41
Okay, about there about here.
00:48
Okay.
00:48
So let's assume that these 2 are the same.
00:51
And the same size now, we need to express the area of the rectangular lot as a function of the length of the fence that device.
00:59
The rectangular law that is x, so we are told to label these ads.
01:05
So these other sites is x and x and these other 2 sites...
