8/9 because there are 36 inches in a yard and you need to convert all the yards to inches and turn it into a fraction. The original fraction is 192/216 but it simplifies to 8/9.
Let each side perpendicular to the wall be x
The parallel to the wall will be 320-2x
the area will be:
A(x)=x(320-2x)
A(x)=320x-2x^2
This is a quadratic with a =-2 and b=320
Maximum area will occur where x=-b/2a
=-320/(-2*2)
=80 ft
thus the width will be 80 ft and the length will be:
length=320-2*80=160 ft
