In this question, we have been given that suppose you have exactly 6 .30 feet of fence, okay, that will be used to build a park with two identical plots of land.
00:14
That's here a fence.
00:15
Okay, so this is how our park look like.
00:18
Since it's here one part of the fence and they are identical, so i consider this.
00:22
Okay.
00:23
So in the first part, what we have to find out, we need to find an expression for the area as a function of x.
00:30
This length i consider as x and this is y and y okay so now we have to find out the area first so first of all we have total length okay so this is x here so total fence length is given to be so total fence is given to be equal to 630 so it will be 3x plus 2y is equals to 630 okay so it is open from this side.
01:01
So we are considering 3x plus 2y.
01:03
So from this y value comes out to be 630 minus 3x divided by 2.
01:09
Now area which is denoted by a of x, we know it is equal to length multiplied with the breadth...
