Can you try to make this information into two equations?

2. anonymous

not really. I don't know where to begin

3. shadowfiend

Ok, so if the length is 2 cm longer than its width, we can say that: $l = w + 2\text{ cm}$ Right? What does the perimeter tell us?

4. anonymous

I am still stuck

5. shadowfiend

Well, what is the perimeter of a rectangle?

6. anonymous

l+w=16 ?

7. shadowfiend

Exactly. (16 cm, in this case.)

8. anonymous

ok. then what do I do?

9. anonymous

w+2cm+w=16cm?

10. anonymous

11. shadowfiend

Sorry, yes, that's right.
