Let say the length of the rectangle is x. The material that can be used would determine the perimeter of the rectangle. Using the perimeter formula you can find the rectangle width
perimeter= 2(width+length)
400= 2(width + x)
200= width+x
width= 200-x
The function to determine the area would be:
area= length * width
area= x* (200-x)
area= 200x- x^2
To find the highest area you need to find out the vertex by finding the value of x when the differentiate of the function equal to zero.
dx/dy= 200- 2x = 0
2x= 200
x=100
If you put x=100 into the area function you will find
area= 200x- x^2
area= 200(100)- (100)^2
area= 20,000 - 10,000= 10000 feet^2
Answer:
5*10^10
Step-by-step explanation:
10 to the power of 10 is 10^10.
10^10*9 is 90000000000
10^10*4 is 40000000000
90000000000-40000000000=50000000000
5*10^10
