Algebra.Com's Answer #583082 by macston(5194)![]() ![]() You can put this solution on YOUR website! W=width; L=length=2W-5cm; P=perimeter=2(L+W)=116cm \n" ); document.write( "P=2(L+W) \n" ); document.write( "116cm=2(L+W) Divide each side by 2. \n" ); document.write( "58cm=L+W Substitute for L. \n" ); document.write( "58cm=2W-5cm+W Add 5cm to each side. \n" ); document.write( "63cm=3W Divide each side by 3. \n" ); document.write( "21cm=W ANSWER 1:The width is 21 cm. \n" ); document.write( "L=2W-5cm \n" ); document.write( "L=2(21cm)-5cm=42cm-5cm=37cm ANSWER 2: The length is 37 cm. \n" ); document.write( " \n" ); document.write( " |
