A farmer will be adding a rectangular corral to his barn. He has 600 feet of fencing. The part of the barn that is attached to the corral is 150 feet long.
Write a function for the area of the corral, A(x) and include the domain
Find the answers for both 'x' and 's'

dunno what "s" is.
So, is one side of the corral (along the barn) 150' long?
If so, then if the other dimension is x, the A(x) = 150x
Since 150+2x = 600,
x = 225
As described above, the problem is trivial, so please clarify.
