The width of a rectangular walkway is 12 ft less than half the length. Determine the dimensions of the walkway if the area is 1080 square ft2.
\n" ); document.write( "***
\n" ); document.write( "Let x=length of walkway
\n" ); document.write( "width=(x/2)-12
\n" ); document.write( "length*width=area
\n" ); document.write( "x((x/2)-12)=1080
\n" ); document.write( "x^2/2+12x=1080
\n" ); document.write( "x^2+24x=2160
\n" ); document.write( "x^2+24x-2160=0
\n" ); document.write( "(x+60)(x-36)=0
\n" ); document.write( "x=-60 (reject)
\n" ); document.write( "or
\n" ); document.write( "x=36
\n" ); document.write( "(x/2)-12=6
\n" ); document.write( "length of walkway=36 ft
\n" ); document.write( "width=(x/2)-12=6 ft \n" ); document.write( "

\n" );
