Algebra.Com's Answer #581254 by macston(5194)![]() ![]() You can put this solution on YOUR website! W=width; L=length=W+2m; P=perimeter=2(L+W)=40m \n" ); document.write( "P=2(L+W) \n" ); document.write( "40m=2(L+W) Divide each side by 2. \n" ); document.write( "20m=L+W Substitute for L. \n" ); document.write( "20m=W+2m+W Subtract 2m from each side. \n" ); document.write( "18m=2W Divide each side by 2. \n" ); document.write( "9m=W ANSWER 1: The width is 9 meters. \n" ); document.write( "L=W+2m=9m+2m=11m ANSWER 2: The length is 11 meters \n" ); document.write( "CHECK: \n" ); document.write( "P=2(L+W) \n" ); document.write( "40m=2(11m+9m) \n" ); document.write( "40m=2(20m) \n" ); document.write( "40m=40m \n" ); document.write( " \n" ); document.write( " |
