Homework Statement
Express the area of a rectangle with the perimeter of 100 feet as a function of the lengh L of one of its sides
Homework Equations
100=2w+2l
The Attempt at a Solution
As far as I can get is,
L = 50 -2w
Just writing the function is a problem, I assume it's something like but I'm not sure, sorry if I'm completely off it's been a long day.
A(W) = (50-2w)(w) = 50w - 2w^2
or
A = w(50-w)
