Answer:
D,G
Step-by-step explanation:
linear function can be written in the form y=mx+b
Let x and y be the dimensions of the rectangle. If the perimeter is 40, we have
We can expression one variable in terms of the others as
Since the area is the product of the dimensions, we have
This is a parabola facing down, so it's vertex is the maximum:
So, the maximum is
And since we know that , we have as well.
This is actually a well known theorem: out of all the rectangles with given perimeter, the one with the greatest area is the square.
To do this you have to fill in the equation
, but you don't know the height, so we'll use
for height. Plugging in the numbers you gave me, the equation is:
. To solve this, we need to find
. To find height you do
. Doing this, we get
=
3.75 ft.Hope this helped!
