Question 671656
l = 4w
p = 2(l) + 2(w)
...
p = 2(4w) + 2w
p = 8w + 2w = 10w
p = 10w
{{{highlight_green(w = p/10)}}}
...
a = (l)(w)
a = (4w)(p/10)
a = {{{(4(p/10))(p/10)}}}
{{{highlight_green(a = (4p/10)(p/10))}}}
...
Without having the value of the perimeter, this is the closest you can get.  Plug in the value of perimeter to solve for area.
