Algebra.Com's Answer #463054 by Cromlix(4381)![]() ![]() You can put this solution on YOUR website! Length = x \n" ); document.write( "Width = x/3 \n" ); document.write( "Perimeter = 2*length + 2*width \n" ); document.write( " 80 = 2(x) + 2(x/3) \n" ); document.write( " 80 = 2x + 2x/3 \n" ); document.write( "Common denominator = 3 \n" ); document.write( " 240 = 6x + 2x \n" ); document.write( " 8x = 240 \n" ); document.write( " x = 30 \n" ); document.write( "Therefore the width - x/3 = 30/3 = 10 units \n" ); document.write( "Hope this helps. \n" ); document.write( ":-) \n" ); document.write( " |
