Algebra.Com's Answer #361571 by TutorDelphia(193)![]() ![]() You can put this solution on YOUR website! We are told the length is twice the width which we write as: \n" ); document.write( "l=2w \n" ); document.write( "We also know the perimeter (which is all the sides added, the length plus the width plus the length plus the width) is 208 which we can write as: \n" ); document.write( "2l+2w=208\r \n" ); document.write( "\n" ); document.write( "Now we just sub in for the length with 2w \n" ); document.write( "2(2w)+2w=208 \n" ); document.write( "distribute \n" ); document.write( "4w+2w=208 \n" ); document.write( "combine like terms \n" ); document.write( "6w=208 \n" ); document.write( "divide by 6 \n" ); document.write( "w=34 2/3 \n" ); document.write( "sub 34 2/3 back in to l=2w \n" ); document.write( "l=69 1/3 \n" ); document.write( " |
