Algebra.Com's Answer #582845 by macston(5194)![]() ![]() You can put this solution on YOUR website! W=width; L=length=2W+9m; P=perimeter=2(L+W)=210m \n" ); document.write( "P=2(L+W) \n" ); document.write( "210m=2(L+W) Divide each side by 2. \n" ); document.write( "105m=L+W Substitute for L. \n" ); document.write( "105m=2W+9m+W Subtract 9m from each side. \n" ); document.write( "96m=3W Divide each side by 3. \n" ); document.write( "32m=W ANSWER 1: The width is 32 meters. \n" ); document.write( "L=2W+9m=2(32m)+9m=64m+9m=73m ANSWER 2: The length is 73 meters. \n" ); document.write( "CHECK: \n" ); document.write( "P=2(L+W) \n" ); document.write( "210 m=2(73 m+32 m) \n" ); document.write( "210 m=2(105 m) \n" ); document.write( "210 m=210 m \n" ); document.write( " |
