Algebra.Com's Answer #125840 by maali40(13)![]() ![]() ![]() You can put this solution on YOUR website! i DON'T UNDERSTAND YOUR PROBLEM what did you say l was ? 7cm.+w .So you say 2l+2w=22cm. so why don't you say 14cm. +2w +2w=22cm. Therefore w=2cm. l=9cm. Course l=7+w 22=2l+2w 14 +4w=22 w=2 l=9 all units the same -no?? \n" ); document.write( " |
