Algebra.Com's Answer #263021 by neatmath(302)![]() ![]() You can put this solution on YOUR website! Let l be the length, w be the width, and P be the perimeter. \r \n" ); document.write( "\n" ); document.write( "l=2*w+3 given \r \n" ); document.write( "\n" ); document.write( "P=2*l+2*w formula for perimeter of a rectangle \r \n" ); document.write( "\n" ); document.write( "P=2*(2*w+3)+2*w \r \n" ); document.write( "\n" ); document.write( "36=2*(2*w+3)+2*w \r \n" ); document.write( "\n" ); document.write( "36=4w+6+2w \r \n" ); document.write( "\n" ); document.write( "36=6w+6 \r \n" ); document.write( "\n" ); document.write( "30=6w \r \n" ); document.write( "\n" ); document.write( "w=5 \r \n" ); document.write( "\n" ); document.write( "l=2*w+3 \r \n" ); document.write( "\n" ); document.write( "l=2*5+3 \r \n" ); document.write( "\n" ); document.write( "l=13 \r \n" ); document.write( "\n" ); document.write( "Thus, the length is 13 and the width is 5. \r \n" ); document.write( "\n" ); document.write( "Therefore the perimeter would be 13*2+5*2 which would equal 36! \r \n" ); document.write( "\n" ); document.write( "I hope this helps! \n" ); document.write( " |
