Hi there, \n" ); document.write( "Make the breadth = 'x' \n" ); document.write( "Length = 6 + x \n" ); document.write( "Perimeter = 2(breadth) + 2(Length) \n" ); document.write( "72 = 2(x) + 2(6 + x) \n" ); document.write( "72 = 2x + 12 + 2x \n" ); document.write( "Collect like terms: \n" ); document.write( "2x + 2x = 72 - 12 \n" ); document.write( "4x = 60 \n" ); document.write( "x = 15 \n" ); document.write( "Breadth = 15m \n" ); document.write( "Length = 21m \n" ); document.write( "Hope this helps :-) \n" ); document.write( " |
