You can put this solution on YOUR website!
we say that
\n" ); document.write( "length = l
\n" ); document.write( "width = l-5 ---> cuz the width is 5 feet less than its length\r
\n" ); document.write( "\n" ); document.write( "rectangle = length x width
\n" ); document.write( " $\"546=+l+x+%28l-5%29\"$
\n" ); document.write( " $\"546=+l%5E2-+5l\"$ \r
\n" ); document.write( "\n" ); document.write( "or we can say
\n" ); document.write( " $\"l%5E2+-+5l+-546=0\"$ \r
\n" ); document.write( "\n" ); document.write( "so, you can find the value of l
\n" ); document.write( "if you struggle to find l, use this solve
