Too Few Pages?

[heavenbound1984]

I was in an undergraduate program where only 1 professor had me do any serious research paper and their page limit was 10 pages. I was not an honors students so I didn't have the opportunity to do any research outside of that. My question is can I submit a combination of a 2 or 3 different writing samples that are about 3-4 pages long for graduate school application?  I may have some 10 page research papers for my associates degree but I think the admissions committee would rather my undergraduate, and those papers are 5-6 years old, my programs' papers are less than 3 years old.
