Question 545532
If l is the length of the longest side of the rectangle, and w is the width (the length of the shortest side, perimeter (in feet) is
{{{perimeter=2l+2w=240}}} <--> {{{l+w=120}}} <--> {{{l=120-w}}}
The area of the rectangle will be
{{{area=l*w=(120-w)*w=-w^2+120w}}}
{{{area=-w^2+120w}}} is the answer.
