I'll give you an example of one, Hopefully this will help you a bit. :)

w(2w+3) = 324 
2w^2+3w-324 = 0 
(2w+27)(w-12) = 0 

w=12, so the room is 12x27

I'm sorry I forgot to put my answer choices on here
a.   L(4-L) = 120               
b.   L(L-4) = 120             
c.  2(L-4) + 2L = 120
d.  2w + 2L = 120
