what do u think

i dont really know i just need help please

wolf1728 · Answer

Okay I'd start with
L = 5*w
perimeter = 2*L + 2*5*w
perimeter = 2L + 10w

wolf1728 · Answer

96 = 2*L + 10w

noahbred · Answer

Ohhhhhhhh 
so its greater than or equal right?

wolf1728 · Answer

Actually all 4 answers are in terms of the width.
My equation
96 = 2*L + 10w
is in terms of width AND length

sorry i am really dumb id get it still

wolf1728 · Answer

Basically all 4 of the answers are stated in terms of width only.
My equation 96 = 2*L + 10w
I don't know how they got 2*L to become 2*w
This is about as far as I can go.
