By definition, the area is given by:
Where,
w: width
l: length
We have two expressions for the length:
Since the length is the same, we equate both expressions:
From here, we clear the value of c:
Then, we have that the width is given by:
Substituting the value of c we have:
Finally, the area is given by:
Answer:
he should order 140 square feet
Here it is given that the width is x ft and total length of the fence is 2400 ft .
Let the length be y ft
So we have
Let A represents area, and area is the product of length and width .
So we get
Substituting the value of y, we will get
Second part
The area is maximum at the vertex, and vertex is
And
And that's the required dimensions .
