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
\n" ); document.write( " $\"perimeter=2l%2B2w=240\"$ <--> $\"l%2Bw=120\"$ <--> $\"l=120-w\"$
\n" ); document.write( "The area of the rectangle will be
\n" ); document.write( " $\"area=l%2Aw=%28120-w%29%2Aw=-w%5E2%2B120w\"$
\n" ); document.write( " $\"area=-w%5E2%2B120w\"$ is the answer. \n" ); document.write( "

\n" );
