Algebra.Com's Answer #639084 by Cromlix(4381) You can put this solution on YOUR website! Hi there, \n" ); document.write( "Make width = 'x' \n" ); document.write( "Length = x + 25 \n" ); document.write( "Perimeter = 2(width) + 2(length) \n" ); document.write( "840 = 2(x) + 2(x + 25) \n" ); document.write( "840 = 2x + 2x + 50 \n" ); document.write( "Collect like terms: \n" ); document.write( "2x + 2x = 840 - 50 \n" ); document.write( "4x = 790 \n" ); document.write( "x = 197.5 metres \n" ); document.write( "Width = 197.5m \n" ); document.write( "Length = 222.5m \n" ); document.write( "Hope this helps :-) \n" ); document.write( " |
