Farmer ed has 900 meters of fencing and wants to enclose a rectangular plot that borders on the river. if farmer ed does not fence the side along the river . find the length and the width of the plot that will maximize the area. what is the largest area that can be enclosed.

Maximum area enclosed will be 101250 meter².

Step-by-step explanation:

Let the length of the rectangular plot is x meters and the width is y meters.

900 meters is the length of the fence which represents the length of the three sides of the plot.

Therefore,

x + 2y = 900

y = meters

Now the area of the rectangular plot will be

A = Length × Width

  = (x)(y)

  =

  = 450x -

We know for the maximum area we will differentiate the area and equalize it t the zero.

= 450 - x

For the maximum area,

Therefore, 450 - x = 0

x = 450

and y =

y =

y = 450 - 225

  = 225 meters

Now the area enclosed A = 450 × 225

A = 101250 meter²

answer: she must produce at least 9,000 windows in order to make a profit of $48,000

explanation:

48,000 - 12,000 = 36,000

36,000/4 = 9,000
