Answer:
85 feet by 170 feet
Step-by-step explanation:
This one relies on Calculus.
so you have 340 feet.
Let x = width, y = length of rectangle
one side of this rectangle will not use the new fence material
so 2x + y = 340 feet.
Area = x*y
We want to maximize Area
Area A = x*y = x*(340 - 2x)
Take the derivative of A w.r.t. x
dA/dx = 340 - 4x
set it to 0
340 - 4x = 0
4x = 340
x = 85 feet
and y = 340 - 2x = 340 - 2*85 = 340 - 170 = 170 feet
Rate of Change and Slope are both the same thing. They show the amount of change on the “y-axis” as the “x-axis” moves. I hope it helps... we learned this in class about a month ago.
