a) Write an equation, using and , to express the constraint.
b) Write an equation, using and , to express the print area of the page.
c) Write the equation of the print area in terms of only.
for a) I am getting 2l+2w=100... I don't know if this is correct.. and for b and c I don't know how to do it.. help?....thanks ahead

a. You are wrong.
Area= LxW=100 or LW=100
b. Printarea= 100(L2)(W3)
for the life of me, I don't have a clue what ".., using and, " means
c. Ibid 
I have posted the question again.. sorry it was "using L and w"
