Creative Landscaping has 60 yd of fencing with which to enclose a rectangular flower garden. If the garden is x yards long, express the garden’s area as a function of the length.
I just can't figure out how to represent the width?

anonymous · Answer

the perimeter is 60 so,
60=2x+2w
where w is the width.
so,
w=30-x
and,
area=x(30-x)
or,
A=30x-x^2
