anonymous · Answer

Can you write an equation that relates W to L according to the problem?

anonymous · Answer

the question is asking to  Set up an equation for the perimeter involving only L, the length of the rectangle

anonymous · Answer

Right, if you can find out an equation that relates W to L, you can solve that equation for W and substitute that in for W in the perimeter equation.
