Farmer ed has 3000 meters of fencing and wants to enclose a rectangle plot that borders on a river. if farmer ed does not fence the side along the river what is the largest area that can be enclosed

area = 1500× 750 =

Step-by-step explanation:

we know area of rectangle  

for length = l m

and width = b m

and perimeter

but one side  length measures is not  required  because of the  river so

He does not use the fence along the side of the river

so we use this formula

Perimeter =  P = L + 2 b

Perimeter is 3000 m

 so area will be

 it  is a quadratic function whose max or min  will

occur at the average of the Solutions.  

 on Solving (3000 - 2b)b = 0  

  3000 - 2b = 0   or b=0

2b =3000

or

The average of the values are

so  for max area  we use b=

The Length is then L=3000 - 2(750) =  3000 - 1500 = 1500

 for max area

length = 1500 m

bredth = 750 m

area = 1500× 750 =

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .

answer: h
