is L =2W + 15 a good equation to establish the relationship between length and width?

Question

anonymous · Answer

provided that length is fifteen more than twice width, I'd say yes.

anonymous · Answer

ok, so basically the formula can be made using whatever numbers? There really isn't a problem, it just says establish a relationship between length and width

akshay_budhkar · Answer

So this equation is taken on by you? or is it provided?

akshay_budhkar · Answer

if the problem says establish a relationship between length and width . why would you choose such an equation?

anonymous · Answer

i just made it up, is that wrong?

anonymous · Answer

i will use it to eventually find a perimeter, so I have to solve for length and width knowing I have an area of 250ft

akshay_budhkar · Answer

No i won't say it is wrong, but somwhow i feel the question is incomplete

akshay_budhkar · Answer

Aha!

akshay_budhkar · Answer

i knew it!

akshay_budhkar · Answer

see that is your question

anonymous · Answer

i just wanted to make sure i was headed in the right direction

akshay_budhkar · Answer

ok this is the way you go ahead now

anonymous · Answer

thank you

akshay_budhkar · Answer

you have the Area = 250

Now we know length x Breadth = Area,,

Taking Length as L and breadth as B

You have L x B = Area

therefore

L x B= 250

Now, the periemter is

2(L + B)...

akshay_budhkar · Answer

so you have to find the perimeter in terms of other variables?

akshay_budhkar · Answer

or do u need to find it in exact constant value?

anonymous · Answer

i got it now thanks...

akshay_budhkar · Answer

umm so what did u do?
