Thank you!

Calculus I assume?
Length*Width= 625
fencelenght= 2L + 3W
W= 625/L
fencelength= 2L+ 3*625/L
d fl/dl= 0=2 3*625/L^2
or L= sqrt (3/2 * 625)
and W= 625/sqrt (3/2 625)
Now, if you are in algebra, I don't see any way of working this except graphing
fencelength=2L 325/L and looking for the minimum.
