Question 69919: The question reads: A rectangular fence has an area of 900 sq. yards. Express the linear yardage required as a function of the length.
Now, I understand that Area=length x width, and that the Perimeter=2(length)+2(width). I can certainly figure the area from the perimeter, but now I'm stuck with this (perimeter from the area). PLEASE HELP!

The question reads: A rectangular fence has an area of 900 sq. yards. Express the linear yardage required as a function of the length.
:
We know that:
L*W = 900
Therefore:
W = 900/L
:
P = 2L + 2W
:
Substitute (900/L) for W
P = 2L + 2(900/L)
P = 2L + (1800/L)
