Algebra.Com's Answer #182318 by mathitutor(25)![]() ![]() ![]() You can put this solution on YOUR website! Let the width = x \n" ); document.write( "Then the length = 2x - 7 \n" ); document.write( "Hence the perimeter = 2x + 2(2x-7) = 34 \n" ); document.write( "=> 2x + 4x - 14 = 34 \n" ); document.write( "=> 6x = 34 + 14 \n" ); document.write( "=> 6x = 48 \n" ); document.write( "=> x = 48/6 \n" ); document.write( "=> x = 8\r \n" ); document.write( "\n" ); document.write( "Hence the width = 8 cm \n" ); document.write( "length = 2x8 - 7 = 16 - 7 = 9 cm \n" ); document.write( " |
