Width = x \n" ); document.write( "Length = x + 3 \n" ); document.write( "Perimeter = 2*width + 2*length \n" ); document.write( "100 = 2*x + 2*(x + 3) \n" ); document.write( "100 = 2x + 2x + 6 \n" ); document.write( "4x + 6 = 100 \n" ); document.write( "4x = 100 - 6 \n" ); document.write( "4x = 94 \n" ); document.write( "x = 23.5 \n" ); document.write( "Width is 23.5 cm \n" ); document.write( "Length = 26.5 cm \n" ); document.write( "Hope this helps. \n" ); document.write( ":-) \n" ); document.write( " |
