"The perimeter of a rectangle is 18 inches. The length is three more than the width. What is the length?" So far I've got:
P=18
L+3=W
And so I think [(L+3)+w]2=P
But I could be wrong...Any takers?

Question

anonymous · Answer

P = 2(L+W)

anonymous · Answer

If you want just one variable (and I think you do) w = L+w means that L = w-3

using daniel's equation P=2((w-3)+w) ya?    or 18=2w-6
and then it is easy

anonymous · Answer

2(l+w) = 18
2(w+3+w)=18  since l is w+3 substitute ..
2w+3=9
w=3

anonymous · Answer

aaak that should be w = L +3 but you knew that

anonymous · Answer

w=3 so l is 6
