See attachment although I gather this is not your question. I did the graph(s) for the function,
G(2w)=(2w)²-2(2w)+1
g(2w)=4w²-4w+1
A) w * L = 112
B) 2w + 2L = 44
A) w = 112 / L then substituting this into B)
B) 2 * (112/L) + 2L = 44
B) 224 / L + 2L = 44
B) 224 + 2L^2 = 44L
B) 2L^2 -44L +224 = 0
L = 14
L = 8
Double Check
Width = 14 Length = 8
2*14= 28 2*8 = 16
28 + 16 = 44
14*8= 112
Correct!!!
If 12.6 was rounded, that means that it was rounded to the tenths place.
You know this because the number has one decimal place, so that must be what it was rounded to.
