Algebra.Com's Answer #224803 by rapaljer(4671)![]() ![]() You can put this solution on YOUR website! Let x= width of the rectangle \n" ); document.write( "5x= length of the rectangle\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "2(W) + 2(L) = P \n" ); document.write( "2(x) + 2(5x)=240 \n" ); document.write( "2x+10x=240 \n" ); document.write( "12x=240 \n" ); document.write( "x=240/12=20 cm. Width \n" ); document.write( "5x=5(20)=100 cm. Length\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Check: 2*20+2*100=40+200=240 It checks!\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "For additional help with WORD PROBLEMS, please see my OWN website by clicking on my tutor name \"rapaljer\" anywhere in algebra.com.
