I understand calculus, I just don't understand how it is applied to solve these sorts of problems.
What is the smallest perimeter for a rectangle with an area of 16, and what are its dimensions?
A=L*W
P=2W+2L
I managed to get the perimeter equation down to one variable like so:
Area is 16.
A=LW
16=LW
16/L=W
P=2L+2(16/L)
P=(2L2+32)/L
and this is where I stop. I just don't see how this can be applied to the situation stated.
