Asymptote is y=0, because when n→-∞, y→0
Answer: 24.63
Step-by-step explanation: To find the area of a circle you square the radius (by 2) and then multiply it by pie.
L=2W+2
W=(L-2)/2
A=LW, using W from above makes this
A=L(L-2)/2
2A=L^2-2L
L^2-2L-2A=0, given A=84
L^2-2L-168=0
(L-14)(L+12)=0, since L>0
L=14
The length of the rug is 14 ft
(W=(L-2)/2=6 ft)
